Too bad it's not actually anonymous at all.

You can easily identify anyone by viewing the source of their FB pic. For example:

  http://profile.ak.fbcdn.net/hprofile-ak-snc4/hs444.snc4/48985_665523839_4409_q.jpg
profile ID is 665523839, which you can plug in to see all their details: http://www.facebook.com/profile.php?id=665523839

Haha yep. Anyone know of a way to hide that? We might have to save the pic from fb. That would be a pain though.
It shouldn't be too much of a pain to do. I do something like this on http://thingist.com (Not caching facebook photos, caching the randomly generated 3x3 pictures that it gives you if you don't connect with facebook [the script to generate the pictures is expensive])

The python to do it would look something like this:

def cache_fb_photo(fb_uid,cache_name):

     import urllib
     import time

     request = urllib.urlopen("https://graph.facebook.com/%s/picture" % (fb_uid))

     photo = request.read()

     photo_location = "/path/to/photo/cache/cache_name"
     cached_photo = open(photo_location, "w")
     cached_photo.write(photo)
     cached_photo.close()

This may or may not violate facebook's ToS. Obviously it would take more than this to actually put it into production, but this would kindof work.
There really isn't a way around that (as far as I can tell) beyond caching them on your server.
Your relaxed attitude to privacy is enough to make me never use that site, sorry.

The fact that it is a 'pain' to make the effort to protect someones identity means you're probably in the wrong business.
