crazy backlinking spambots?

[manchesterguy]

have you ever seen spambots generating backlinks to your site?

if you let a blog or forum unattended, you'll find spambots tha register and post links to their usually pornographic sites. however, they also put links to YOUR forum on other sites in return.

this causes a massive list of backlinks generated from other forums, and u dont lift a finger.

anybody ever experienced somthin like this before? i'm getting 100 links a week by these spambots who i dont even know.

Spam prevention
* Flood control: This forces users to wait for a short interval between making posts to the forum, thus preventing spambots from flooding the forum with repeated spam messages.
* Registration control: Some forums employ CAPTCHA (visual confirmation) routines on their registration pages to prevent spambots carrying out automated registrations. Simple CAPTCHA systems which display alphanumeric characters have proven vulnerable to optical character recognition software but those that scramble the characters appear to be far more effective.
* Posting limits: Limit posting to registered users and/or require that the user pass a CAPTCHA test before posting.
* Registration restrictions: Applying careful restrictions can seriously impact bogus and spambot registrations. One approach consists in the denial of registration from certain domain extensions that are a major source of spambots such .ru, .br, .biz, or freebase addresses such as "gawab.com". Another, more labor-intensive, consists in manual examination of new registrants. This examination looks at several indicators. First, spambots often delay email confirmation by several hours, while humans will confirm promptly. Second, spambots will tend to create user names that are unique, and unlikely to already be used in the forum, preferring "John84731" or "JohnbassKeepsie" to the much more common "John." Third, using a search engine to investigate, one finds hundreds, if not thousands of profiles using the spambot login name, sometimes with the diagnostic spam post, or "banned" label.
* Changing technical details of the forum software to confuse bots - for example, changing "agreed=true" to "mode=agreed" in the registration page of phpBB.
* Block posts or registrations that contain certain blacklisted words.
* Be wary of IPs used by untrusted posters (anonymous posts or newly registered users). A useful technique for proactive detection of well-known spammer proxies is to query a search engine for this IP. It will show up on pages that specialize in the listing of proxies.
