Note that on rare occasion, a user will receive a registration feedback message of something like:

Registration denied, this forum runs an active policy of not allowing spammers.
I think I've figured out why. There is a forumplug-in called “vbstopforumspam” that automatically checks a world widedatabase of known spammers and will send this “you are a spammer” response backif the user has a username/ip/email address etc in common with a known spammer.E.g., if "eddie345" is a known spammer user name with the wwDatabase, then registering *here* with that username will result in a blocked attempt. I’ve disabled the pluginfor now on our site and hopefully our other anti-spam methods willsuffice.
