I think this is related to Dick Costollo's new efforts to "get rid of trolls." *<p>My experience:
I tried replying to a (non-spammy) tweet with "woah. this is awesome." and received this message:<p><pre><code> This request looks like it might be automated.

</code></pre>
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.<p>The support instructions suggested I change my password but that hasn't helped either. Can someone at Twitter help?<p>* <a href="http://www.theverge.com/2015/2/4/7982099/twitter-ceo-sent-memo-taking-personal-responsibility-for-the" rel="nofollow">http://www.theverge.com/2015/2/4/7982099/twitter-ceo-sent-me...</a>
