I was playing Hardcore conquest too from their servers, so official hardcore servers and i got banned about 4 games in.
(context) The Hardcore servers im reffering to are the ones you select a gamemode from the multiplayer tab and click to play which automatically connects you to a game. its filled with bots except maybe 5-6 real players per team racking up 50/70+ kills per game due to the bots being predictable with how they move around the maps. So a well possitioned tank and boom, 50+kills easy.
Im wondering if the Anti-cheat flagged my account for leveling up too fast due to the amount of kills vs the bots in an official lobby with Full XP... I've no idea why they even alow these kinds of servers if you get banned for playing on them. Let alone official ones....
