So you run some sort of bot that automatically bans accounts and you don't even double check manually that it makes sense? If something is automated to auto-ban, then it can be automated to include what it caused it to autoban within the ban message as well.
So write something then! All the new developments is taking place in the new software.
It is a sad period for someone who have perma-bans due to only a single plagiarism in the past, but for users whom actually repeatedly plagiarised, I think that they won't have chance to complain and come back.
Now, with such a ridiculous perma ban period, please spend your time to code a bot to create Ban Appeals (with template of Ban Appeals). Lazy guys can use the template easily and only have to change ID or username to finish their Ban Appeals. The question OP should consider is using the Ban Appeal Template results in another plagiarism or not. Think of it before coding such a bot. Lazy guys whom perma-banned might support and use it.

Why would you work for free helping a forum that doesn't give a fuck about their users? We've had people waiting literally for years trying to recover their accounts which were hacked and now this. And it isn't like many of the people in charge here aren't rich and with the proper resources to get all of that fixed. But let me spend my (non nonexistent) free time fixing it myself while under the fear of losing your account permanently because you posted the wrong thing 7 years ago.
