We've received a couple of spam messages on our forum today. I suspected that they were spam and stuck them in to google to confirm. It looks like the same message has been posted over and over in the last 12 hours. Is there anything that can be done to stop or discourage these spammers above and beyond the normal controls? If you're interested, the text I googled is: Hey, admin! Why you banned my old account?! WTF???
