I saw spam directed at my blog to http://www.quizilla.com/users/Online-Blackjack-Casinos/journal/ It redirect to http://win.topfindit.org/search.php I wonder, what is topfindit.org is? How do they make money?
The majority of Blogs have nofollow, however there's still alot that dont plus some scripts target other things as well like forums, guestbook, referer logs etc.
a) from nofollow you still get traffic b) despite the concept of nofollow, search engine spiders are still crawling thru nofollow links, including Google. Maybe the pagerank is not getting passed to the same degree, but it still helps your site get spidered and arguably somewhere in the algorithm it is getting counted as an inbound link.
I am a programmer. I can provide that kind of service in exchange of info on how to do it. Please show me a sample of spam that succesfully get 10000 of pages indexed.
I resell some scripts that may do what you need in regards to Guest Books, and Forums. PM me for info
