My two friends and I just experienced this first hand for the very first time, and it annoyed the shit out of us. We outflanked and shot someone in the hills east of the powerplant in Elektro, then when he was down on the ground and bleeding, he disconnected instantly and over the course of 10-15 minutes continued to reconnect and disconnect to the server. Some of his clan members (K.R.I.T) came to his rescue, and we shot AND downed another 2 of them, but similar to the first they abused this system and avoided death. Finally, the first one we had shot reentered the game and we were able to kill him before he could disconnect and thus gained some loot (although very little compared to what we could've had).. Honestly, it was simply a very distasteful thing to do. Especially considering that these were ALL members of the same clan, I would have expected that they would have tried to kill legitimately or at least sucked it up and taken it like a man. In a way, I get it. The one person we were able to loot had a shitton of gear. Military grade sniper rifle, silenced M9, rangefinder, GPS and more. But man, it was 10-15 minutes of pure frustration over these scumbags trying avoid death. Fuck 'em. I'm not totally into the whole "too many disconnects and connects = bad things happen to your character", as we have had some trouble connecting to servers sometimes. But a short timer, perhaps 10-20 seconds when trying to disconnect, sounds very reasonable.
