My Gravatar is a photo of my daughter and me. I like it very much, and want to continue to use it on most of the blogs where I leave comments. However, one blog on which I would like to comment, which is a WordPress.com blog, has a rule against "personal photos" as avatars. I am trying to figure out a way to comment on this blog, without the photo of my daughter and me showing up as my avatar, while still being able to use that image on the other blogs I read. I contacted Gravatar, and their only suggestion was to create a new email address specifically to use when I comment on this one blog, and assign another Gravatar to it. That doesn't seem like a practical solution to me, especially if there are a lot of other readers of this blog who also have personal photos as their standard Gravatar.
Is there another solution? Is there any way that I can comment on a WordPress.com blog and somehow tell it NOT to use my Gravatar?
