I have a pseudonym FB account that I am forced to maintain for this reason (specialist interest groups). It's the new phpbb even though it completely sucks as a forum tool. The same questions get asked over and over. But worse is better I guess.

I went to great lengths to keep my account completely anonymized, so the suggested friends list is a hilarious cross-section of global randos. Of course being a pseduonym account I could be banned at any moment.
