The official Twitter Developer's account tweets:

That's it. That's the tweet. No indication what rules are being enforced, despite the question being asked several times.

I’m excited to see where the brains behind #Twiterrific can go in the Fediverse. 👏

Tweetbot, Twiterrific, Echofon, and other third-party Twitter clients have failed to work for many people since late last night, and the social network has seemingly not notified the apps' developers as to why.
