Is there a way to get all users that: 1) uploaded an avatar or 2) have a Gravatar? I want to filter users that doesn't meet one of these conditions.
I forget to mention that this is for Buddypress. Anyway, I found an answer for the first condition, this is the
bp_get_user_has_avatar() function that checks if a given user ID has an uploaded avatar.
Now I need only a Gravatar validation for the second condition.
