Some popular subreddits have pretty petty mods and there is no real recourse to being banned from the sub even if you explain your position and why it didn't violate any posted rules; if anything challenging their decision seems to send most in to a tizzy.

the real challenge will be users attempting to use the system to shut down other subs or posters within. there are some seriously hate filled subs that people do try to get shut down with false claims of reddit rules violations; namely vote manipulation

given they also freely allow multiple accounts will they shut down all accounts they can prove are related? how do they handle multiple accounts on one IP where the users truly are distinct
