CleanTalk provides lists of spam active IP/email addresses which were seen by the service in spamming on the websites, and lists of domains that are promoted using spam. Often, many spam bots send out messages disguised as normal and can be very difficult to define what spam is. You can check the IP/email of questionable users in our lists to find out their spam activity.

Check of spam activity for IP/email

Spam active IP can participate not only in spamming but also to participate in other types of attacks, such as fraud, DoS, DDoS, SQL and PHP injections, etc. and email addresses can be used to send spam via e-mail.

Black SEO

  • This will be useful in the definition of spam in messages if the text messages there is a link with the domain from the list, then with high probability this message is spam.
  • Also you can check your domain to make sure that it is not moving with the use of black SEO. Some SEO companies may use black SEO to promote the site and place links using spam. As a result, you will receive a report about the presence of thousands of links, but then you can lose credibility and get penalties from search engines.
  • When you buying a domain will also be useful to check the history and reputation of the domain. It is quite possible that before the sale of the domain, the domain was promoted by placing links in spam comments.

How does the database work?

Blacklisted IP, Email, Domain addresses are generated automatically based on spam activity of a sender on the Internet. The database records are added in two ways:

  • If automoderator sites has ruled that a particular sender/registration is a spammer, then its IP, email, as well as all of the domains in its message are entered into the database. Each record is assigned 1 point.
  • If on manual moderation message/registration the site moderator removed the publication (deleted the account), then each record of IP, email and sender domains included in the database is assigned 1 point.

After reaching 3 points (on 3 different sites sender activity was calculated as spam), the sender is automatically entered in the blacklist.

Removal from blacklists is also automatic, by reducing the number of points to 2 or less, or when no spam activity is recorded over 45 days.

To protect your site from spam bots you can use one of anti-spam plugins CleanTalk.
