I thought I had blocked a sandbagger, but I just played the same sandbagger again. Apparently, I can bock them from accepting my games, but the system does not stop me. Am I supposed to keep a list of sandbaggers on my own? On KGS, you can block sandbaggers easily. How hard would it be to include blocking me from accidentally accepting their game?
This is a serious question because blocking them means you do not have your time wasted. This is something sandbaggers are completely unaware of; that they are wasting your time.
