A British journalist who was banned from Twitter after publishing the email address of an NBC executive was reported by the social network, it has been claimed.
It had previously been thought that NBC had seen the message and reported it, but The Telegraph has claimed that the social network informed NBC of the tweet first.
Guy Adams, a foreign correspondent for the paper, send the message after criticising the American broadcaster's Olympics coverage.
NBC's Olympics broadcasts have been criticised on social media for poor commentary, and for cutting key sequences of the Opening Ceremony including a tribute to the victims of the 2005 London bombings.
In one of the tweets Adams encouraged users to send their opinions to Gary Zenkel, the president of NBC Olympics.
Subsequently Adams' account was suspended.
But now, in an email to the Telegraph, the VP of communications at NBC, Christopher McCloskey, said Twitter alerted NBC about the message.
The revelation, if true, raises troubling questions about the social network's neutrality.
Twitter is covering the Games with NBC, providing top tweets by athletes and commentators in exchange for promotion.
Adams, speaking to the Telegraph, said: "If what NBC is saying is true, it undermines everything that Twitter stands for and is an absolute disgrace."
Twitter told Adams that his account had been "suspended for posting an individual's private information such as private email address, physical address, telephone number, or financial documents".
In response, Adams said: "I didn't publish a private email address, just a corporate one, which is widely available to anyone with access to Google and is identical to one that all of the tens of thousands of NBC Universal employees share."
Twitter reportedly wants Adams to apologise before reinstating his account.
