Peter Da Vanzo has posted information on XSS Redirects & SEO. Peter linked to two documented methods of exploiting comments and links at blogs and other sites. The two links include; XSS and Redirection Attacks, which makes for a nice and interested educational read and Moveable Type Backlink Exploit that makes me a little depressed (running MovableType and all). Point being? The nofollow attribute, created to slow down link spam, has not worked, IMO, I actually had to pull comments and trackbacks completely from my blog after 3 years of them being enabled. Sad.
