[tor-project] Research paper on differential treatment of anonymous users

[Griffin Boyce <griffin@xxxxxxxxxxxxx>]

Hey all,

  Just wanted to point to Sadia Afroz / David Fifield et al's research 
on differential treatment of anonymous users -- such as CloudFlare's 
blocking of Tor users.  Unfortunately, it's not "just" CloudFlare (which 
holds substantial market share) and it's not "just" Tor users who are 
impacted by these things.  It's a good read:

  One curious finding is that some sites only block large exits.  I'd be 
curious if an intended side effect were the ability to say "Oh we only 
block 15% of Tor exits" rather than saying "We block [>>15%] of Tor 
connections". Thoughts?
