This was suggested a while ago. But the implementation is apparently difficult. Players who receive a wrong channel silence longer than 24h can send a help ticket for a possible reduction.
If you're posting here in forums, you weren't banned. You were just silenced. Banning is something else entirely.
Genuinely who asked why you are “trying to protect minors that manage to make it in” because ban and/or fire that person. That being said you can have a 17+ game with 17+ content while still protecting kids with minimal effort but this over-policing/parenting when you’re community is 20+ at this point is pointless, aggravating, and game killing.
