Is that it strives to enforce/encourage roleplay - ALL THE TIME. I can't think of any other multi-game that legitimately tries hard to keep it policed and functional. I do feel bad for your case, but after attention was drawn to the person and stuff, that is a much easier line in the sand to identify. Can't agree it's overreacting while at the same time wanting players NOT to break the 4th wall.
Now, for all things overreacting: I think asking for a ban so you can't give in to playing FTW *clap clap clap*
