Okay, this is getting ridiculous, there was so much spam today that when I was marking it I got given this message!

This would all be fractionally less irritating if it was possible for a normal user to change the subject used in the thread listing but AFAICT the only way to make it obvious to others that a thread is spam would be to change to using a differently named user account.
What do we have to do for this to be taken seriously?
