<p>Do friends and nearby users even appear in that case? I thought they only appeared when you were logged in and looking at your own page?</p>

<p>That's the whole point of the discussion, gravatar gets information -on me- even though I don't have gravatar enabled because the other users have it turned on. So gravatar knows that has viewed gravatars of nearby user 1, nearby user 2 ...</p>
<p>The alternative to being restrictive would be to proxy accessing the gravatars (I haven't checked if their ToU allow that, iirc caching isn't allowed).</p>
