Hundreds of real Twitter accounts “locked”

I think this is related to Dick Costollo's new efforts to "get rid of trolls." *

My experience: I tried replying to a (non-spammy) tweet with "woah. this is awesome." and received this message:

  This request looks like it might be automated. 
  To protect our users from spam and other malicious activity, we can't complete this action right now. 
  Please try again later.

I tried to tweet that screenshot but my account was immediately locked. I followed the "unlock account" instructions and entered a confirmation code from my phone but the account was immediately locked again.

The support instructions suggested I change my password but that hasn't helped either. Can someone at Twitter help?
