3 things:
1. That looks like it was from a demo server and the user in question was a demo user (no +)... That means no bannable key, and no issue of toricred manipulation.
2. I've seen a similar thing to this occur due to some sort of lag/connection problem. Since i didn't see any chat from the person in question, maybe thats what occured here?
3. Why all of a sudden the run and tattle about so-and-so threads? If its an issue, server logs will bring it to bear. Quit being a bunch of tattletales...
