Semalt Expert Describes How Bots Were Born From Spam

Michael Brown, the Customer Success Manager of Semalt Digital Services, has tailored in the article some compelling facts about spam origin.

The first spam message was sent in the 1994. At that time, Laurence Canter and Margaret Siegel wrote a program that posted an advertisement for their company’s green card lottery paperwork services. They sent this message to all the Usenet News Group members, and there were over six thousands members who received this message.

Due to the unique way the message was posted, Usenet customers failed to locate the duplicate copies, and the users saw copies of the same messages in all the groups. At that time, the commercial use of internet and online resources were not common. Plus, the access to Usenet was far more expensive than the others. Lots of users felt that the commercial-seeming messages were good for nothing. They not only took up their time but also had cost a lot of money to the users.

Later on, the green card incident caught everyone’s attention. Arnt Gulbrandsen developed the concept of cancelbots, which was later compared to the content of the messages of the spam messages. Afterwards, it was forwarded to the original sender for verification. Canter and Siegel repeated the process again and again. The users could not combine the spam and failed to cancel the messages in the Usenet server. Anti-spam measures were also taken, but all in vain.

It was just the beginning of the commercial spam and Usenet spam. Before April 1994, Sedar Argic replied to a number of messages saying that he had denied the Armenian genocide. Apparently, it was not a wise decision, and things were needed to be changed by the whole.

The early form of Usenet spam was the messages that were being sent to lots of users on the internet. On the other hand, Cancelbots worked on the identical messages and tried to verify their source. Eventually, a time came when the Usenetters using the advanced technology found the solution to this problem. Russian scientist Andrey Markov invented a bot in 1913 and used a variety of pages to generate filters.

It took the spammers no time to understand that the cancelbots were stumped by adding the random junks at the end of every message. At that time, the spammers moved the Usenet to a variety of emails, ensuring that they were attacking all the European and American email IDs. More and more people dedicated themselves to figuring out the nature of spam and tried to fight the spammers online. Non-human accounts were created with the aim of researching the behavior of hackers on the internet. New technologies were developed, and various spammers were destroyed with their servers. On the other hand, the spammers figured out the problem and developed far better technologies than this. They also developed methods against the filters of Google Analytics.

For spammers, Bayesian created messages to convince the users that they are legitimate and reliable. Long and short strings of unrelated words were created, and this technique became common and widespread in no time.

In 2010, Amazon introduced the eBook store online, and its server was flooded with lots of spammers. As of now, so many techniques have been introduced to deal with a large number of spammers and hackers online.

Semalt: How To Block All Ads Systems For Free?

Browser ads are not only a nuisance visually but pose a significant security risk. There are several moral implications of blocking these ads. By implementing ad blockers on your browser, you cut down on the salaries of those coding, designing, and providing the content that you usually view for free. The very ads you wish to block are the same ones that provide the funding for placing everything else online. Nevertheless, the frequency of these ads ultimately undermines the browsing experience.

Michael Brown, a marketing guru from Semalt, provides here few points to remember:

  • Ad blockers are very legal which means that they have no restrictions. The decision on how to block the ads rests entirely on you. If you do decide to use an Ad Blocker, make sure that it is clean, and will serve you well. However, they have some limitations.
  • Funding for Ad Blockers emanates from a single organization or person. Therefore, one must conduct their research on the company before using their service. You must make sure that it will ethically block all ads for as long you are signed up with them. There are cases where ownership of the Ad Blocking service changes and the new owners receive premiums from some companies to skip their ad addresses.
  • Adding an extension to a browser will undeniably slow the browser down. However, if you have an efficient machine, this should not worry you. Otherwise, you may have to restrict yourself to two or three tabs at the same time.
  • Extensions require constant updates which take up more of your time and resources.
  • Ad Blockers cannot function well without subscriptions. You must select a list of websites that you wish to have blocked and manually add them to the block list.
  • It is not possible to run a system-wide Ad Blocker if you run multiple browsers.

Luckily, there is a better solution which is free of charge with no subscription. It blocks ads for the entire system forever. It does not need a software to install it, meaning it will not slow down your system.

Here’s how:

Install the host files from MVPS. It alters known ad server URLs with a null character. When the computer tries to access the internet, it will return this null character meaning it does not download the ad which will, in turn, save you a lot of time and resources. The following is a process on how to block ads manually using the MVPS method.

  • Confirm you have administrator privileges. Open the “Run” Console by pressing the windows key and R concurrently.
  • Enter “Services.Msc” and locate the “DNS Client” option. Right click on it and scroll down to “Properties” and then choose to “Stop.”
  • From the “Startup type” drop-down menu, choose either “Manual” or “Disabled.” Experts recommend the Manual option.
  • Apply the new settings and restart.
  • Replace the host files in “C:\Windows\System32\drivers\etc” with the updated ones.
  • If the anti-virus or windows defender attempts to take action against the action, decline.

You now know how to block ads without an ad blocker whenever you are on the internet. Make sure to update the host files regularly and replace them in the specified directory.

Semalt Expert Explains How To Block Darodar In Nginx

Darodar is a famous referral spammer that clogs up the Google Analytics accounts of both small and large sized websites with malicious and low-quality traffic. Unfortunately, Google Analytics cannot filter it out properly, and your site’s search engine ranking decreases in no time. Some miffed webmasters and bloggers have talked about Darodar activities, providing details about how to block it. Even a few WordPress plugins have been introduced to eliminate the Darodar traffic, but here is an easy and outstanding way of preventing it in nginx.

With this method provided by a top expert of Semalt, Julia Vashneva, you can get a tiny bit of revenge from the spammers.

What should you block?

The first thing is to identify who you want to block. In your Google Analytics account, you can set up new parameters and check the quality of your traffic. You have to make sure that you eliminate the visits with a low session duration and 100% bounce rate. Sadly, botnets like are difficult to deal with as their bots and spiders are present everywhere on the internet.

You need to get the list of sites that are possibly receiving fake traffic. It is not so easy especially when you have a large number of websites. Prepare the list with names of sites receiving referral spam, and decide which ones you should block. The main culprits we have found that you should include in your list are,,,,,,, and You should block all of these websites to protect your Google Analytics reports.

Send them out

You should bear in mind that will never respect your Google Analytics account and don’t obey robots.txt. That is why you should redirect their spiders and bots back to their own website and mess with their Google Analytics account by implementing special codes. Alternatively, you can use URL shortening services ( for redirecting them back through random URLs, confusing their Google Analytics to a great extent.

Honestly speaking, they might not have been originated from the developers and makers of Darodar, but you should redirect their traffic to protect your own website on the internet. Given the unapologetic attitude on Facebook and Twitter, you should not feel bad or guilty. It is possible to set up individual statements for all of the referrers, ensuring your protection in search engine results.

Test everything properly

Last but not the least, you should test everything properly. Since you have messed with the nginx config files, it is good to test whether you have blocked what you wanted to block or not. It is important to not create false matches. Instead, you should focus on blocking Darodar in your Google Analytics account.

Once you have set up the redirects and errors, you should use the Server Status tool for checking the responses of the server for multiple referral strings. If you have any other idea in your mind and want to share with us, do not forget to throw us an email or comment in the box below.

Introduction to starting a company in Singapore

So you’ve gotten around to wanting to register a company eh? Congratulations! It’s a huge step in the right direction, but it’s important to do so correctly, so before you head over to incorporate your business, let’s go over some details that are worth knowing of.

First of all, the type of business or company you want to start depends on a number of factors. Are you the only one starting the enterprise, or do you have partners and co-founders? Do you want to have a formal board of directors or shareholders, or do you wish to be 100% in control of all decisions yourself?

It’s also important to know where the liability should lie. If you register a single person company it’s possible to be indebted privately for the company’s losses. But on the other hand, you can also take profits when you wish and how you wish.

Tax is another important concern. Let’s take Singapore for an example. The way the government has set up tax deduction on companies, is simple. Up to S$100.000 can be exempt during the first 3 years, if you qualify for this package. The government rolled out this scheme to help Singaporeans bootstrap small businesses, and also foreigners have taken kindly to this idea.

So let’s take a look at what’s requires for incorporating a company in Singapore:

  • ACRA is an organization run by the government to help oversee businesses and their incorporation. They require 3 different company name proposals. This is because names have to be approved beforehand.
  • You also need to appoint at least one director. To start a company in Singapore you need to have one of the directors to have been born there, but it is not mandatory that they control a part of the company or shares.
  • You also need a real registered address for your business. This address can often be just a rented office address, or anything more than that.
  • You also need to open a back account in the country, and use that for your businesses interactions.
  • Finally, it is mandatory to choose a company secretary, and if the company is a single person business, the owner cannot also be the secretary.

These are some of the requirements, now let’s take a look at the benefits:

  • Any private limited company in Singapore is their own legal entity, which means that directors and shareholders will not be held personally accountable for any losses, lawsuits or other liabilities incurred by the business itself.
  • Singapore has offered a S$100.000 tax exemption scheme for new businesses for the first 3 years, which means making money is easier than ever.
  • Many companies in the country offer to appoint Singaporean residents to your company, and be there physically when required by law. This means you can open a company as a foreigner, without ever setting foot in the country.
