If Forums provide "Dofollow BackLinks" to your websites and blogs, than why don't you. Well i must say again this is big theft of my list. http://www-marketing.blogspot.com/2008/08/list-of-125-do-follow-forums-100-no-no.html Each and every links you have posted on your post are already there on my blog. But let me tell you i have decided to make a worlds biggest dofollow forums list, Currently it's containing 140 Dofollow forums and Will Soon updated with more 50 forums. You are following "blatant-content-plagiarism" technique.
Firstly I can't follow your link, secondly I have found all these forums from searches on this forum, then I went and manually checked the PR of each one.
He indeed doesn't post a do follow link to these forums. An open question is also which forum to post to, to gain best results.
I see my forum is on your list and many other dofollow lists, which explains the over spamming in the last 2 months. The funny thing is, I made it nofollow a month ago as a result, yet no one seems to bother to check...and I just keep deleting spam, and banning IP's.
