They suspended 12 of my accounts for no reason (generic ToS violation) only because they were linked together using TweetDeck. None of them violated anything, and appeals are still progressing 2 months later. 8/12 unsuspended - 4 more to go.

What was especially sad was that I used tweetdeck to improve my security - can use the account without sharing my password. However, twitter penalized me for trying to improve security by using it as a discovery mechanism for my remaining accounts.
