I don't play WoW at the moment. I played off and on (mostly on) for the first five years of the game, and I'll play again for a while once the expansion comes out, then probably quit again, etc. Anyway, especially a few years ago when I had the time and inclination to play more, I was fairly active on the forums. My husband still plays, and so do a ton of my friends. So I'm really familiar with how the forums work and what people are like there. This is a terrible, terrible idea. Especially if the intent is to discourage trolling, there are much more effective solutions available. Some of the reasons why it's terrible have already been brought up, but a bunch of people who are obviously not familiar with the WoW forums have muddied things by making arguments based on incorrect assumptions, so for the sake of having an omnibus "this is why it's bad" post, here we go.

As long as there have been video games, there have been ways to cheat in them. They range from harmless codes that change the weather in Red Dead Redemption to serious hacks that make your aim perfect in Counter-strike. There are different layers of the severity as well; while wallhacking will get you a VAC ban on Steam, it’s likely that no one is going to care if you turn on The Sims 3 and give everyone in your town some free Simoleons.
