I don’t know but the mastodon documentation does not mention this: https://docs.joinmastodon.org/user/moderating/#block-domain

Personally I’d expect that anything I post on social media is being public and freely accessible by anyone if they want to. If you don’t want the information to be used by others you probably should not share it with the world.

It’s really great. I tried it out an dits the prefect mixture of LaTeX with markdown and functions. The only issue I see is that it wasn’t developed for dynamic screens.

But HTML + CSS or anything more advanced than markdown would be great.
