I think this is a bad idea. It's fascism disguised as progress.

First, RIU has a reputation system already built in, and while it's not foolproof, it does give a very quick glance at what others have said about said advice giver. Banning people for giving bad advice will not encourage them to learn, it'll only keep them away from a rich source of knowledge.

Second, who's to say the FAQ are absolute gospel anyway? The purpose of a community message board should be for open discussion, not cultism and/or elitism!

Third, anyone who takes advice from an unknown entity has a few lessons they need to learn anyway. If you take advice from a newb who doesn't know shit and it messes you up, then next time, don't take the first advice given to you! Do a bit of research, learn to identify qualified experts! That's life on or off the internet, man.
