i saw a toot about it elsewhere but i can’t find it so: basically don’t trust mastodon for things you want to stay Actually Private. instance admins can read DMs, and instance admins can read the private posts of anyone their users follow. this is sort of inherent to the current architecture. and for all twitter’s sins, i trust the admins to not leak random people’s DMs more than i trust every instance admin ever.
Don't let the name fool you. All the pornography here is legal, and much of it is hand-written. No fascists, no bigots.
