Don't know if you've noticed, but in the last few days there's been an onslaught of spamm on the forum. A lot of the spam is generated by these spambot programs, and the forum software had to be updated to recognize these spammers. I'd say that only a small percentage of them would actually get through to post their spam in the forum threads, but in the last 2 days alone, there's been about 60 to 75 fake accounts that were created. So the mods have been busy banning/deleting these fake accounts.
And BTW, we totally appreciate when you guys report spam to us because it helps us to act on it immediately.
