I don't think everyone who was posting hate comments was really a hater. ^^
It's more of a psychological thing. The facotrs were simple...
A) The forums were closing down
The mods were being stricter
C) Getting banned/Suspended has no meaning because servers were going offline
D) Some people started to troll knowing there is no risk, thus influencing others
E) We all should have a conscience;
knowing the factors above people were posting their frustrations, and just living out on the edge for once..
Mainly because there wasn't much to loos.
