The microblogging site removed Adams's Twitter account following comments he made criticising NBC's 2012 Olympics coverage, reports The Guardian.
NBC has come in for heavy criticism for its presentation of the Games, specifically for its decision not to broadcast events live.
Adams had previously written a number of tweets slamming NBC's overall coverage, including one in which he urged followers to write to the NBC Olympics president, which resulted in the ban, according to The Independent's deputy editor Archie Bland.
"The man responsible for NBC pretending the Olympics haven't started yet is Gary Zenkel. Tell him what u think!" Adams wrote, along with Zenkel's email address.
Bland posted on his Twitter: "@guyadams will have piece on heavy-handed suspension of acct up soon. For clarity's sake, came after he mentioned NBC bod's email address."
The Opening Ceremony of the London Olympics was held on Friday, July 27, and featured well-known British stars including Rowan Atkinson and Sir Paul McCartney, who closed the ceremony.
Atkinson caused the biggest Twitter spike when he appeared in his iconic role, Mr Bean, during an homage to Chariots of Fire.
