After a few months of thinking about it, I have removed the permaban that is given out after reaching 100% warning points. The ban will instead be a one month ban instead of a permaban and it will be appealable. A permaban doesn't really make sense outside of specific circumstances (illegal content, infiltrator, or being a fakecel) so I have adjusted the system to reflect that. People can still be manually permabanned by a moderator for severe violations of the rules, but this is now the standard.
Also, anyone permabanned for reaching 100% warnings can appeal to be unbanned due to this new policy.
Edit: It seems that there is some confusion here. The only thing that is changing is that members that get to 100% warning level will only be banned for a month instead of permabanned. Mods will still be able to permaban when they see fit outside of the warning system.
