Unfortunately, signing up for a Forum, going through the vailidation process, and then senting PM's to members is the new way to spam a Forum.

Chris, is looking into solutions to prevent such attacks.
In the mean time, I have been "upgraded" to help on "SPAM control"

If you/(any member) receive SPAM, please notify Chris (nonrev1) or me with as many details as you have, so we can review the complaint and take appropriate action.

Again, we would like to thank the many members of the Forum for alerting us to this recent SPAM attack.
