I interest with the site about guard spammers on web or blog. And i try to use it at my blog here. Just information for yours to use it too. Discription : Robots WWW (also called vagrants, spiders, crawlers or robots) are programs that crawl the web pages linked to recover steadily. When a robot spam visit their website, blog, forum, etc., all pages and sites linked to it will search for email addresses.
All you have to do is link to this page so that every time a spammer's robot scans your page, it will be sucked into this one.
These links you'll be collecting e-mail trap robots sites that are fed with an infinite loop almost false dynamically generated email addresses, mostly in known spammer owned domains! This will make their lists harvested practically useless and no commercial value.
If i wrong about this articles, please confirm me at your comments posting here. Thanks for attention.
