Feedback is worth what??? [Outdated]

Someone please explain to me the value of feedback when it is abused so much. I rarely leave negative feedback. I rarely get negative feedback. I don't complain when the negative feedback I received was ridiculous...I figure people can decipher for themselves it's validity. But now...I am alittle miffed. I left an honest negative feedback because the player was making crude, rude, and disgusting comments. I thought others should beaware of this and should they decide to play him, they can atleast ignore the chat. I am very disappoint to find...that my feedback was deleted because it was unwarranted. Deleted because of what....and for those of you who are interested...sorry...you can't read the chat from the game...because it's been deleted too. I think this means...feedback is worth...what???
