I don't think a single infraction of hate speech would warrant any consequences, it would need to be a multiple offenses before punishment is doled out. This punishment could just be a temporary loss of voice communication privileges. Eventually if they are a habitual offender, it could lead to longer loss of voice comms, and then eventually a repeat ban.

Producing identity verification documents that many times over and over is not something a 13 year old will likely be able to do, relatives would certainly raise questions from those relatives as to why they need them.

I see the ridiculous Orwellian service is being the anti-cheat software we have to run already.
