No, I was not being a smartass. I really think you're doing something terribly wrong if you're getting 500 emails a day from rejected bots. Have you just tried a simple Q&A? That eliminates about 100% of our bots, and no email notification is necessary.

That leaves real humans as our only remaining source of spam. And when you ban these guys, they won't be able to read your 'shame' forum anyway so why bother?

And the few bots that may register but never post - and thus don't get banned - aren't a problem anyway. They just swell our ranks which isn't a Bad Thing.
