Spammers target all social networks. They literally overran an elgg site I have and I’m rebuilding with WP/BP. A few still get through with the latest BP and anti-spam and custom profile fields, not a lot, two or three a day, but that’s nothing. I found about 600 in my first month in my users that never made it to the surface. As for the few that did, having a couple fill in custom profile fields is really helpful. The bots that do sneak through fill those two spots with gibberish, in my case age and location, so it’s easy to identify spam members.
