The problem with keeping trolls guessing by not sending them a clue (in the form of a dws has declined your message
response), is that some people get decidedly more annoyed (and annoying) when they feel that other people aren't listening. That could result in behavior that negatively affects other monks.
This is a tough one. If some troll were to starting pestering the CB with "why isn't Footpad responding to me? what have I done?" messages, it puts me in the position of either having to /ignore them, or get involved as a third party to try to quiet the mess down. Neither of these I want to do.
What to do? Are you on the road towards banning users?
