you asked good question.
Forum Profile Links are working if it is made for 3 way link building. You make 1 Good page daily with your backlink and optimize this page daily with forum profile links, social bookmarking, and commenting.
By this way, forum profile link is working. Direct linking is worthless, you go and check all top websites of your niche. You won't get any valuable forum profile link except good signature links with informational posts.
