Recently an alarming number of Twitter users have been suspended for doing nothing wrong. This originally started in April as reported by the conservative news site Human Events and has begun to recently spiral out of control beyond the realm of politics and simple account suspensions.
The original attack is quite simple - get enough Twitter users to report a user for spam...and the target user's account is suspended. According to Human Events this attack was originally being used by left wing liberals to silence right wing conservatives for expressing their views. While I will not get into the political issues of this and why this goes against freedom of speech...something I will mention is that a "defense network" is being built to help protect against these attacks.
