Backlinks form forums the next target?

We all know that posting in forums is a free and easy way to get backilinks.
Now ggogle have already penalised forums as far as PR goes, do you think that they may do the same with backlinks generated from signatures etc?

I don't think so. I believe they do not count all signature links anyway.

It wouldn't really surprise me if Google tried to do this. Google appears to be chipping away at methods of generating backlinks until left with pure organic linking, not that I think they achieve this.

Exactly, there's no way they can pin an organic link from a paid one. In all seriousness, they should just forget about links and move to something else. This whole link crazy is driving me crazy

It amazes me how they can fish out specific links, if they indeed doing this, to get just pure normal linking

well, i have links in forums and a forum, i did a lot of link building yet my pr dropped

I think there is no major direct benefit SEO wise from forums. The benefit comes from users clicking your links and getting direct traffic via that click and also potential further traffic if that user decides to link to your from their site.

Never man. How can one blame a person related to you when you commit mistakes. Like that, if there is something wrong with Forums it goes with forums itself.If you still want to be on the safer side, remove the signature.

Do you have any evidence to prove your statement?
