It's pointless even appealing a permaban in the current system. If they're told what they were banned for and that it's permanent then most except the truly desperate probably wouldn't even bother trying.
90% of banned users know the real reason why they were banned, they obviously Knew when they tried to cheat the system by copy and pasting in the hope of getting unnoticed,but when eventually caught and banned still make an appeal here in meta about their ban
So what's to say that telling them the obvious reason which they already know would derail them from making redundant threads about the ban,that doesn't just yield anything
Whichever way the ban message appears,banned users would still make threads about their ban
Only if the rules of ban appeal is removed,and any user who post about a ban with his/her alts would get banned immediately
That will end the whole furore
