The problem with that is, that WordPress does not really know if the Avatar is updated 🤔

As a (temporary?) workaround, could you not subsequently also update your user profile (like change your bio, or even just press the Update button, in WordPress, after having updated the Gravatar image)?

Wouldn't that cause WordPress to push an update to followers' servers?

Not sure if that'd get those servers to (re-)download the image ... Could still be Mastodon is like, "Meh, same URL, don't need to check if maybe the image itself has changed." (If so, that would be a Mastodon issue.)

A "better" solution could be to eventually have WordPress check (like, once a day or so) if the image hasn't changed (by downloading it and compare the [binary] data or a hash thereof or something with an earlier version).

Another possible solution might be to use a local avatar, maybe? Through a plugin? Although I'm not sure if updating it would trigger an Update request. I guess it'd depend on where you set it, too.
