We recently put installed some anti-spambot features into the forum to stop spambots from registering and posting spam.
The features are working....however...hundreds of bots had already registered and every once in a while they would post something. We would remove the spam and delete the offending spambot's account, but I didn't want to keep doing that. Nor did I want to go through the memberlist and analyze each user with zero posts and delete the ones I thought were bots. That would take days.
So... to remove all spam and future spam coming from spambots, we had to delete all of the accounts with zero posts...99% of which were spambots.
If your account was one of the live person accounts with zero posts that was deleted, I apologize that you were a casualty of war...a victim of friendly fire.
No biggie though...you can just re-register. I apologize for any inconvenience. But if you'd have posted once in a while, this wouldn't have happened.
