1) I visited several "about me" pages, barely legal links seem to be a problem. I don't think those members logged in for a second time, maybe the "about me" page should be checked in the future.

Those members did also leave their Skype/icq data.

2) A few days ago a suspicious thread was removed. The member wasn't a newbie and every single of their comments was meaningless. This can surely happen coincidentally, and I'm really sorry if that happened, but please be careful who contacts you.
