Since we're removing gravatar from MBS, This is possibly relevant:
There is still gravatar on the blog, which is a wordpress site. We might want to deal with this, if it's possible to implement in the same vein as MBS-9725 or if a different approach is necessary/wanted.

I went digging and founds some links/articles that talk about the issue:
