It is spam and the easiest way to beat spammers who employ this stupid tactic is to not only nofollow all the profile links but also make user profiles invisible to non-logged in users i.e. including search engine bots.

Let the spammers try to inflate forum registration count as much they want, it won't really benefit them in any way!
