The intended audience of the bad review is usually the staff and players on that game. The player has usually been cut off from communicating their displeasure inside the game. As has been said many times, players have the right to logoff. Well they do enjoy another right too. The right to whine, bitch and moan on mud forums (well as long as mud forums and listing sites remain liberal in regard to who uses them). Being that forums are primarily read and written by mud staff, it almost guarantees a predominately negative group response regardless of the complaint. And some admins will respond by loosing their flying monkeys to do damage control on the reviews or forums. Of course if players weren't terrified of really speaking their minds on the muds they play that'd probably cut down on "AnonymousCoward" reviews.

I think it's all very amusing.
