Yeah I had a script running by accident that uses the "Negative!" voice command when you kill someone.
I got silenced because it was considered spam, which is completely understandable, I asked to get un-silenced and was told to stop spamming voice commands and I would.
So I did. Actually hardly said anything for the rest of that map.
Then the map switches to Avalanche and Allies wins the round in like 3 minutes, I went 7-0 as support and was editing a bind on the 2nd round and suddenly got banned.
Also, thank you for your quick reply and I will check later if there is any more info.
