Adding the editing of posts is a good feature addition, in my opinion. I wonder if posts that have been edited display that they've been edited, though.

It sounds like they've thought about these risks, and I would assume that the UI element for accessing the "history view" looks different if there is no history, i.e. the current version is the only version.

What if poster is evil and also a server operator? Could be the post edited silently and seen from user in other server?

That would cause havoc; specifically because other instances can forward your message. So the original message will always float around in retweets and replies. It'll probably be very visible.

A server operator will always be available to edit the content in the database.

Yes, there are visual indicators that the post has been edited, similar to how it is on GitHub.
