i kinda figured it would require some sort of verification process so we are not banning people for little reason (a record system of bans from communities on the system, via a ticket or rep sheet) and maybe a script to ban if banned from x number of comms, or after it has been reviewed by an admin. though right this minute might be unrealistic implementing this in the near future

from the documentation there is a way to ban a user from the site, but only admins have access to it, might be worth trying to coordinate with them to ban them
This, it’s a server specific patch, give the devs some time to update it and it should probably be back
