Answer 2

Request the gravatar with a query parameter of d=404 (default to 404)

https://www.gravatar.com/avatar/nogravatarexistsforthisemailhash?d=404

This will return a 404 if the email does not have a registered gravatar. If one does exist, the image is returned with a 200.

So make the request, then map a 200 response to true, 404 response to false.
