Any website is going to need some level of moderation by necessity. Illegal content, incitement, disruptive spam, dox, etc. The basic stuff to keep the site functional. The problem is the people most attracted to being literal internet janitors are the ones who get off on the "power" they feel it gives them. So you end up with all kinds of stupid fucking "unwritten" rules and restrictions.
You end up with a site that has more overmoderation than fucking Twitter. On Twitter you can put a "NSFW" tag on a post and have it automatically hidden. You have less freedom than fucking Twitter.
