There is no "private data" on mastodon, I think it gets communicated enough that admins will have access to direct massages. it even says to you "Posts on Mastodon are not end-to-end encrypted. Do not share any sensitive information over Mastodon."

if you want more, use the IM of your trust ;)

True MOST ppl don't want to host, but they are a few that like it and even get money for providing a public service. So I don't have to host smth, I just have to find someone hosting it.
