GTA V online's time has come.Like GTA IV or Halo 2 before it the game has become a breeding ground for trolling, glitching and modding.It is beyond saving and must be allowed to die. GTA V online must be destroyed.
To start off with, trolling happens and there's nothing anyone can really do about it unless you've got special powers to remove them. Secondly, this is GTA online and like other online MP's, it's bound to have the old glitch here and there and of course, there will be those players that like to use mods.
All this stuff has happened ever since MP began, you get all this nonsense on SA:MP, MTA, etc but there's really nothing use normal players can do about it, just deal with it.
If GTA online should get "destroyed" as you put it because of the stuff you've listed, might as well "destroy" all the other Multiplayer's like SA:MP....
