Bot Spam Protection

Bots across the Internet cause a lot of spam for website owners and organizations. Common spam bots include comment spam and referrer spam. 

• Referer Spam also known as 'log spam' or 'referer bombing' is a kind of spamdexing (spamming aimed at search engines). [From Wiki]

• Comment Spam is typically characterized as irrelevant messages posted by spammers as comments on forums and blogs.

• Form Spam provides protection against fake/automated form submissions.
