It's not a rule, it doesn't even apply to moderators in the first place either. It'd be like using basketball rules for soccer. Can't be a bad example of something that doesn't exist.
The reason Hiroko gave for it, I have no idea if it is the reason why there is a six month wait limit, I thought it was because moderators didn't want to be hassled all the time to change names every week or so.
Stufflikehearts - He is a Sith Lord. I love Blood Lord :3
Jeffffey - Blood, you look at the information someone says, look over what really happened, and reply in a way that makes them realize what they were really thinking.
Light10s - Blood Lord! Your avatars are becoming more epic. You make me feel like getting on all fours and submitting my loyalty and obedience to you.
Fievel - Numerous campaigns and conquests, countless bodies decaying after the abandonment of victorious battlefields. Such is the life of Blood Lord.
Dusk_Imp - Blood Lord is like a celebrity here. Everything he does is pure awesome. ALL HAIL BLOOD LORD
Doctress Who - Why couldn't there be a Blood Lord in every forum? It would make life so much easier.
