I havent seen any yet...When people get banned for glitches like this, you usually see it all over the forums. So I would imagine that it hasnt happened yet

most people are being smart about it
they arent getting mroe than 19,999xp per match
if u go over 20k xp in 1 match you'll get stripped and banned for 2 days
i havent gotten banned from that glitch, but i have been banned for naother one for getting 25k in 1 match

I get about 60K a game and went through 3 prestiges in 4 hours, about 40-45 kills a game then leave, i expect a ban soon seeing how im #3 in all time search

yea me and a friend ended up getting banned for 48 hours. it could of been for a couple of the private match games. yes we got to greedy and played more then 5 games of each glitched types. what is funny though is that me and my friend honestly didnt get that high on the leaderboards. and what else is funny is that with the ctf glitch treyarch made it possible to do it and they knew it. but they wanted to sit there and let people do it so they can catch people and reset them totally. but thats ok, that just means we found a easy way to deprestige lol. (sorry have to look at getting banned and reset on a good side).
