Keith, OT, but for the second time this year, someone is newly (just as of today) using one of my secondary Gmail accounts as their FB user ID. They don't appear to have access to the Gmail account -- and I've newly killed any concurrent sessions and then changed its password and security Q/A to be sure. So, I don't know how they're accomplishing this. But that Gmail account received the sign up confirmation messages and is now filling up with friend confirmations. Any chance you could plug me into someone relevant at FB, as this appears to be a recurring problem without a ready explanation? Email to pasbesoin at that gmail place. P.S. As best I can determine, my systems are clean, and I've no other problems/compromises that are apparent. There appears to be something borked with the Facebook account creation confirmation process.
