it means the person who has been permanently banned had broken the rules and somehow gotten banned 4 times (temporarily) within 3 months, excessive bans like this lead to permanent bans
Also since youre new here, I just wanna put this out there... dont reply to ban appeals unless you are trying to help the person who got banned, or something of that sort, it gets messy and staff definitely do not appreciate having people spam important threads-
though I'm not a staff member I thought this guy should know, I'm sorry for replying here again
