They removed all links that are created in the user profiles?
Really?
Can't believe it...
Edit: Apparently, this is what they're up to. "January 27th, 2012 -- We are taking temporary preventive measures to stop the increasing trend of spammers targeting the site. For the time being, external links within user profiles will be disabled until a long term solution is devised."
Who knows when they'll come up with a solution. I do hope they give all the external links back.
