I hate it. Quite a lot people have reported a few months ago, that they only get "anonymous visits". At the moment this also happens to me and I start asking me, if almost anyone has switch on this "privacy feature" of not showing their visits to the pictures they've watched.
I mean, come on, why do you click the pictures at all if you do not want its creator to see you??! Or ist it just hits that come from search engines... really out of IP, so to say?
