Uncensored nudity in the "random posts" section of the top page
Straight-up genitals. This probably should not be allowed to happen even when a user isn't doing NSFW flagging properly and/or an instance is not enforcing it.
True, but you can report that is not flagged as nsfw and the moderators of either instance can properly flag it. Which seems to be the main cause of these issues? I have nsfw content disabled on this account and have ran into unflagged nsfw on the front page. I'm not against nsfw content being hosted, I just personally don't want to see it. The point isn't to get it taken down or anything, just properly tagged so the people who don't want to see it, don't.
