Thought it was funny when people reported that the game is bugged when their hits make no more damage because they got SB.
If your account got enough reports or is flagged your account will get shadow banned, similar to what CoD does. This will be apparent with decreased damage from your bullets. You need around a whole magazine to kill a single player. A few hours or 1-2 days later your account will get permanently banned.
If you see that your account is SB you should stop cheating and play like a dumbo. That would slightly decrease the chance of a permanent ban.
And no so far BattleBit doesnt issue HWID bans.
