Is it only for public posts, or also private ones ?

I wouldn't post private information in a public area, but I happen to exchange adresses or account numbers in private messages, as I would do in emails. Not on X since I'm not on the platform, but any other one will do the same if not already done (e.g. Reddit).

I use private Twitter posts as a password manager, so this new development is very concerning to me.

... just kidding. There needs to be xkcd about something like this.
