Moderators will always check the reports for legitimacy. There will be no bans where it's not cleat that a user is a plagiarizer or at least I don't know any user being banned without reason.
Ban is the hardest punishment and therefore an individual checking by mods is inevitable.
Moderators cant ban Users , only Global Mods and admins as far i know !
So those autobans are global mods? That so many bans per day. Are they in a competition?
