Fair enough. How about some 'Unpost' or 'Unsend' link with a 120s timer like you have in DMs of some sites? 'Recalling emails' comes to mind.

That's pretty good feature if you ask me. There was a client that implemented it. Plebstr I think.
This would have to be set on the client side. I’ve asked Damus to allow an optional delay when posting. Nostur has an Undo button with a short timer on it. So far the developers don’t seem too interested.
