I've deleted quite a few users from the forum as they were being used for spam only and had no posted messages. If I deleted your account by mistake, please recreate it (sorry!).
do you keep logs of everything?
Pixel has done a backup of the database before removing many other users.
Anyway, none of the deleted users had posted any messages and they were clearly bots.
i would make a script that automatically band and deletes a user if one of their first posts is that xrumer crap.
