is there any chance of adding the attribute rel="nofollow" for external links posted in the forum messages.(To help SEO). This would stop getting bad search engine rankings based on bad websites linked to by forum users,
good reason.. any chance?
with a help by a friend i found a alternate solution for this problem by adding a deferrer like anonym.to the link. So links posted by users will be opend by using the deferrer anonym.to. and can´t be followed.
