No idea, it's weird they reacted that way because I reported all three of the CP posts on that account instead of just the one though. Evidently they have some questionable staff.
I reported an account that was posting CP and they banned ME for report abuse and let them continue posting but removed one of their CP posts. Reddit is a cesspool.
Reddit was fun but the admins are insane, I reported an account that was posting CP and they banned me whilst claiming they took action against that account yet it is still up. Classy.
