That’s the one of the few rare cases where anonymity is important. Add whistlelowers etc. to the mix but these are edge cases that can have specialized mechanisms.

For many cases the default approach could be good enough though. Your identity will be encrypted in the system and when the moderators of a specific platform think that you are a trouble, they lock you and remove your content but they don’t know your identity. It’s up to you to unlock your account by revealing your identity.

So, you can simply post to places that are not hostile to you and you stay anonymous. Russians journalists can post to American forums for example.
