I have deleted the avatar from everywhere I can find it in my gravatar profile, which now shows a grey default. The avatar still shows up next to my profile drop down menu on my blog and I can't find any way to remove it. I've cleared my cache, logged in and out, and waited overnight but it still shows up, meaning it is still being stored on a server somewhere. To be clear, I want to delete the avatar image from everywhere, so that only a default avatar shows up.
The blog I need help with is strangetractor.wordpress.com.
