Question about permanent bans ...

I'd suspect this to be the MWLB's doing. They have the power to oppose whichever player they want, and they share the view/thoughts of a common Mapler, unlike the O-so-holy Game Masters. Since, presumably, Nexon doesn't have a permanent punishment for R&R offenders (such as this site's Ban on Sight policy), I'm assuming whoever's banning you is doing it manually, and they have my thanks.
