The Independent scribe was barred from his account on Monday after posting the email address of a top NBC exec, following a number of tweets criticising NBC's coverage of the London 2012 Olympic games. The post was then retweeted by other Twitter users in protest.
Adams alleged in an article that NBC only complained about the message after Twitter had alerted the broadcaster to it.
Citing an email a Daily Telegraph journalist had forwarded to him from NBC, Adams quoted an NBC spokesman as saying: "Our social media department was actually alerted to it by Twitter and then we filled out the form and submitted it."
The account was reinstated earlier today, with Adams revealing that he had received an email from Twitter saying: "we have just received an update from the complainant retracting their original request..."
The journalist claims he did nothing wrong in posting the address as it is a corporate one, using the same basic email format used by other employees at the company, something he claims could be worked out by "anyone in possession of 30 seconds of free time and access to Google".
NBC paid $1.18bn (£752m) for the US broadcast rights to the Olympics and came under fire for its decision not to broadcast the Games live, as well as replacing the Opening Ceremony's 7/7 tribute with an interview with Michael Phelps.
It had formed a partnership with Twitter prior to the Games to create a page highlighting tweets from celebrities, athletes and fans during the event.
The social networking platform had been criticised for its stance by other journalists, with Guardian special projects editor Paul Lewis saying that the ban "jars with the company's claim to be the free speech wing of the free speech party".
Twitter and the Olympics have been making the headlines elsewhere this week, with Tom Daley's abuse on the site at the hands of a 'troll' subsequently leading to his arrest.
