I'm sorry, but it looks like your ban was actually caused by a bug. Other people were getting banned because of it as well. You were the first one, and since we never saw this happen before, we assumed you were hacking (as the AC told us you were holding a chainsaw, while you never spawned one). The bug was due to an update to not replace weapons when spawning them. So, when you spawned a sniper (/sniper), the game tried to set your weapon back to the previous slot. Since you were holding a golf club, which is in the same slot as the chainsaw, the game tried to reset your weapon to the chainsaw (which you didn't have). That triggered the anti-cheat, thinking you had a chainsaw, while you didn't spawn one.
Anyway, we're sorry for the inconvenience it caused you, you're unbanned now.
