Howdy All!
You know, you can remove the files from the server along with the 100 other wavs in the admin plugin, then war would be more peaceful place.
You could also write a small script that filters the things people say like the spamming script and just expand it to prevent these types of spamming too. Just for fun, have the server send 200 "Do not spam the server" messages to the offending person that way they get spammed for trying to spam. That would stop them pretty quick. ;D
Cheers.
