From an email I sent about recent site activity:

Interesting side effect, since rolling in the new spam prevention I'm 110% effective at registration for the last day or 2. (I say 110% because I'm getting some false positives)..

Then everything stopped. All of the spam registrations went away for a couple of hours...

...then I got slammed with a storm of delivery failure notices. Apparently I angered the SPAM gods and they went from fake registrations to sending out on my behalf. I'm at 27,980 at the time of this writing. (No new spam registrations during this whole storm).. interesting to see how things shake out and if the fake registrations start back up again.

The number died down at 194,270 failed message delivery messages (someone sending with my domain name as the sender/reply to.

Sadly fake registrations started up again but still most are getting caught.

Question. Is it possible to auto ban users based on their email domain suffix (.cn)

I know I can prevent them from signing up with this using the out of box, but I prefer to let them continue to use a suffix I can recognize and am ok with bulk banning and then dump them in ban right away. The spammer (unless they read this post :-?) will not know why they are being banned and this will be quite a big net for me at present time.

Any suggestions?
