Everyone is dong fine! Just report the spam post (click the red flag) and move on. Don't reply, and don't quote the post.
It actually doesn't matter what severity you give it, at lease not the way our system is presently set up. I'd probably choose a higher number if I were reasonably sure it was spam.
Our members are very good at reporting spammers. The only time I've run across an unreported spammer's post is when it had just been posted, and that is rare.
Ridgerunner, I'm actually not sure what you're talking about, and not planning to search in FAQ for it at the moment. Maybe the list of mods, which is not in FAQ that I know of, it's in a sticky in the BYC Website and Feedback forum. But there is no need to PM a mod. The fastest way to reach the next available mod is always the flag, the report button.
