Whenever we get an annoying user, it usually doesn't get very far. Since most of my visitors are high schoolers, it happens more than at a site like this. Not too often though. But, if someone even looks at the line and thinks about stepping over it, my moderators pounce.
Like, if a new user makes a post using all caps, within minutes (usually) a moderator will bust up into the thread with lights blazing. (We use

in our posts when we're moderating.)
However, we do have members that, while posting relevant and good information, still manage to annoy people with the stupid things they write. So this hack will find a home at Drumlines.org. The way I look at it is, if they want to use it, it's there. If not, then they don't have to. It's always best to give the option rather than not.
