i tried it earlier but the clueless kept responding and then some people wanted to keep abusing him, which was a noble cause so i didn't press the issue.

it will work, i think an important component to pulling it off is making sure that newer people know not to reply. after each new topic he starts, someone follow it with a disclaimer that nobody is to reply to dr.pornz's nonsensical spamming. just one of those, but after each post from the doc should work. if someone replies, PM them warning them never to do it again and not to respond to pornz's reply.

you should really be able to read through a forum and not have to avoid half of the topics.
