There are more than a couple of members who send occasional "spam reports" to us moderators by clicking the little "REPORT POST" icon at the bottom left of spam posts.
We often kill spammers before they are even seen by you guys, but sometimes they slip through the cracks (or I go snowboarding for a day or 2 and they go crazy while I'm gone).
Reporters - you know who you are! Just wanted to say "THANKS!" We appreciate the heads-up.
(Here's what the "REPORT POST" icon looks like -- pic from another site -- in case you're wondering...)
