I would say a permanent ban would be the best option, hacking ruins player's experience and the fun of PvPing. Getting unbanned should be something difficult in hacking punishments, because, as you said rule breakers break rules again and again, so they don't understand that there are rules and that they have to follow them. Also, rules are not really clear, in some servers /rules says that hacking is a 7d ban and others 5d, etc, that makes staff members impart different lenght in punishments for the same offence. There should be a unified rules list in the forum and the /rules should be updated. Agree on most of what you said, nice post.
