Last time we did it, it was Because there were genuinely people out there who got permabans or 6+ mont bans for petty shit, and there were about 4 years worth of these bans. A second mass unban would see a sizably small at best portion of the community free’d, but nowhere near as many as before.
Staff need to just respond to ban appeals, people who want to play but are banned typically would just make a ban appeal.
