8chan like every forum ever has dumb moderators who dont know how to do their job / over extend their hand (and the moderation position of web forums seems to attract people with certain mental disorders that make them seek out perceived microinjustices which the definition thereof changes from day to day)

there were a bunch of sites mirroring 8chan to steal content

these were useful because they had both a simpler / lighter / better user interface (aside from images being missing), and posts / threads that were deleted would stay on the mirrors. being able to see deleted posts / threads was highly useful as the moderation on such sites tends to be utterly useless and the output of a random number generator. it was hilarious reading "zigforum" instead of "8chan" in all the posts as the mirror replaced certain words to thinly veil their operation. they even had a reply button that didnt seem to work or was just fake.

tl;dr the web is broken and only is good when "abused" by proxy/mirrors
