   Yes, agreed.  I have to wonder what the origin of this sudden policy 
is.  And, is it a policy directed at anonymous users?  Or is it just 
certain IPs being marked as malicious and blacklisted?

   Well a clearly this isn't a definitive "this user is not up to 
anything bad" setting, but rather they need a more holistic approach 
here.  Their policy here is very opaque.  But if the goal is to avoid 
automated activity (follow/unfollow/spam/messaging etc), then there are 
other approaches that could work just as well.

   Why not captcha these activities if the user comes from Tor or an 
identified proxy?  Is this a pain in the ass for users?  Yes.  Is it 
going to prevent them from expressing themselves anonymously online?  
No.
