BuddyPress.org

I’m looking to do the same things, so maybe I can be some help. For now, I may be putting the avatar moderation on back-burner and focusing instead on removing gravatar support. The low-tech solution is to delete the user’s avatar from the server.

Gravatars don’t make a lot of sense on BuddyPress, since they are stretched and look blurry on the member pages. There’s a plugin that disables the gravatar for WPMU & BP: https://wordpress.org/extend/plugins/disable-user-gravatar/ Haven’t tried it with BP 1.2 yet.
