Your first comment makes literally no sense whatsoever. Every single instance of "account sharing" is within the knowledge of the account holder, otherwise that would be hacking. You're literally just rewording "allow account sharing" but trying to manipulate the staff by giving the reasons in a different way of approaching it.
"Oh yeah I account shared with him but I didn't know I was account sharing" - then it's hacking?
Also, what happens when you share an account and then change the password randomly and drop communication with the people whom you're sharing with? Then do you become the hacker and they say you robbed them of their progress/money? This is why it gets out of hand and our small team (count SNR MOD/ADMIN) hasn't got the time to deal with this small bullshit. Better to just remove the ability entirely.
Perma Mute
This is an awful idea, it would make someone want to quit entirely, which isn't our goal when issuing punishments. Infractions are here to decipher how long you should be banned for, which are issued fairly. (If you believe they're not, again, you can appeal).
Why would we waste time muting people who just keep on chatting shit and never learn their lesson from mutes?
Discord now has a feature to have group chats, so this is an alternative. But I'd agree with what Dan says here as server creation is free with Discord and it really isn't hard to figure out how to set one up.
