Yeah saw all those coming in last night. Removed FB connectivity and they kept coming. Changed how to register just now requiring the "type the two words you see" feature and seeing if that helps. We used to have a box that required someone to type "Go Jazz" in it which slowed bots but they figured it out.
Adding FB connectivity can NEVER be a good thing.
One thing I really have a lot of respect for in regards to this board is that it's growth was done organically. I mean, do we really need more users? Regardless of the amount of new users, for the most part only the same users post.
