I still can't believe R* allowed players to do this. They changed the system from GTA IV and RDR where kicking someone required a majority vote (and people actually see the votes) to allowing any player to anonymously kick any other player of their choosing. It's no longer "Vote To Kick", it's just "Kick".
That's why I, along with many other people, have been getting kicked out from nowhere. It was generally thought to be a bug, but it's actually a part of the game. What the hell were they thinking? I'm guessing this was supposed to be an anti-griefing tool, but it's the ultimate griefing weapon. You could just be minding your own business exploring the world and some jackass kicks you out just for sake of it.
Once GTAO works for everyone, this will be the bane of any player's existence. This needs to be fixed ASAP before GTAO becomes a griefer heaven.
