Twitter has apologised for its role in suspending journalist Guy Adams's account.
Adams, who writes for The Independent, had his account suspended after criticising NBC's coverage of the Olympics, then posting the email address of one of its executives.
Despite Adams's account being re-instated earlier today, many criticised Twitter for its stance and pointed to NBC's Olympic partnership with Twitter as a possible reason behind the ban, an assumption that was partly confirmed by the company in a statement earlier.
The company re-iterated that a corporate email address still constitutes private information - something that Adams contests - but confirmed that employees were involved in reporting the tweets to NBC.
The statement said: "We want to apologise for the part of this story that we did mess up.
"The team working closely with NBC around our Olympics partnership did proactively identify a tweet that was in violation of the Twitter Rules and encouraged them to file a support ticket with our Trust and Safety team to report the violation.
"Our Trust and Safety team did not know that part of the story and acted on the report as they would any other."
The statement signed off by re-iterating the company's commitment to free speech, saying: "We do not proactively report or remove content on behalf of other users no matter who they are. This behaviour is not acceptable and undermines the trust our users have in us.
"We should not and cannot be in the business of proactively monitoring and flagging content, no matter who the user is - whether a business partner, celebrity or friend."
General Counsel of Twitter Alex Macgillivray later sent a tweet to Adams, saying: "Let me to add my personal apology for your suspension."
