Fix the problem you change the outcome.
Re-tool the signature code so that the link on the member's profile page is the only external link and their massive internal forum contributions that built value for you over time (compelling content) is rewarded by providing their profile solid link juice.
Now instead of having thousands of worthless external links the user has a powerful profile link based on their own worth to your website and that changes Google's impression of your domain.
Sorry, my english knowledges did not reach to understand this.
The forums arent mine and I can only delete the signature or keep it.
In one of the forums I have deleted my url to use as a signature, this means the signature disappeared on all of my posts in that forum, however stayed in profile, google had 60 links indexed.
In the other forum I have deleted my url to let users view my website, this meant the url disappeared from all of my posts, but whats even worse even from my probile on that forum.
sorry but I did not understand your solution.
