dog1962, the reason you provide 5 examples is to help the mods out. Yes it is obvious, but if you don't than the mod either has to let him go or go do all the work for you. If you really want him to be punished you should list look through his list of ratings, view the games and list 5 games he left ratings for and explain how they were wrong (aka "Player did not deadbeat or talk rudely in chat").
It's not that we don't believe you but the mods work for free basically so they can't be expected to fill in everyone's cases for them.
Ironically he left me no rating when I beat him so maybe he only rates people if they are really bad which is allowed? We would know for sure if we had the examples listed.
