I suppose it's not a ridiculous idea, but the mods will probably just say to accept your ban and do the time. I think people would then just try spam the reports in to get unlocked. Would they all have to be reports that were handled successfully? Getting 50 good ones correct at 100% probably isn't as easy as it sounds and would probably take most users a week to achieve anyway.
well it will take 2-3 days to report 50posts, and its not necessary that they get 100percent correct, they can get atleast 60percent correct, if they make less than 30percent correct they get to report more 20posts and if they report less than 10percent correct, they get a permanent ban. Like this we can make this system
