Comments under characters @armory

Hey guys. I think it is a great idea to make such a thing where registered users could leave comments under character tabs at armory pages.
This change would affect the website activity and probably make many people think about acting bad to other players.
As example such kharma police can help sorting trash players before inviting them into pug raids.
It's just too obvious for me that this small thing can bring a lot of fresh social air on every realm.
What do you think?

Comments would be too much and easily abused. Staff wouldnt want to have to worry about moderating the comments. Probably just a 5 star rating system or so. Anything simple like that.
