Twitter backs down at last - but why did I get banned?

[Commentary] Twitter's decision to “un-suspend” my account allows me to Tweet again. That's happy news; or, to use the vernacular of social media, *happy* news. But there are plenty of things that it does not do, some of which have set awkward precedents.

Twitter has not yet explained how exactly the tweet that led to my suspension is supposed to have broken its "privacy policy," which forbids users from posting "private e-mail addresses" but says nothing about corporate e-mail addresses, which is what I had actually shared. It has not explained how its decision to suspend me can be squared with a clause in its own privacy policy which states that: "If information was previously posted or displayed elsewhere on the Internet prior to being put on Twitter, it is not a violation" of the company's terms of service. There are wider issues at play. The company has yet to properly address growing suspicions that its decision to suspend my account was motivated by a business relationship with NBC. The firms are running a cross-promotion throughout the Olympics. Was that why it chose to ignore its own rules?
