Every day there are so-called spam robots (this is a fact of the software) to look across the Internet, trying to find the e-mail addresses to add to their databases. Then they can send their large numbers of unwanted messages.
Place one or more of the buttons and banners on this page on its website. The best place is the index page or the most important page in which robots spam is more likely to enter your site. You can also place the code in more than one page. If you manage other website, such as a blog can also help fight spam with placing a link to http://www.antispamweb.com/stop-spam.php
The result is that code-spam robot will enter into your site and find fake e-mail addresses. Thus automatically database of spam will be occupied by their own robot with addresses unavailable. We use thousands of different domains owned spammers. Because after some time addresses will be updated with new directions that will be added to the database of spam. The spammer will be forced to put your site on the list of places that should be ignored by the spam-bot (this will be explained later under the heading "Fight Back")
I hope this articles will help us.
