You can tell when you look at the lobby leader boards. The glitcher will be listed as a non-prestige and he will have a level like 30 or something like that.
Around 80% of the master prestige people that I see glitched and have a lower level in the lobby leaderboards.
Another way is to look at the time played. Most have 4 days 5-11 hrs. They all used the same file to glitch.
Another thing, they will not only get reset, they will be reported to Sony. And Sony will perma-ban them for messing with the user-data file. Read below, the glitches will get their consoles banned forever from BO2, LOLLLLLLLLLLLLLLLLL..... There is only a first offense, lol...reset and perma-banned.
Any user who runs a modified version of game code or uses a modified game profile is subject to penalty.
First offense: User will be permanently banned from playing the game online, will have their stats & emblems reset, and will be blocked permanently from appearing in leaderboards.
Console users who modify their hardware or profile data will also be reported to console manufacturers. PC users on Steam will be reported to the Steam enforcement team.
