There are a lot of lessons we can learn from the downfall of tumblr for the Fediverse aswell. I am glad there are Mastodon communities which welcome explicit content creators. But some of the comments for that video suggest that they aren't able to connect to people outside of that bubble, since these people's instances might block NSFW ones.
In addition to that, blocking tags like #abuse is an awesome mental health feature which should definitely be embraced by the Fediverse and Lemmy in particular.
