Twitter declined Monday night to comment on its suspension of accounts of two popular sports publications, Deadspin and SBNation, but correspondence it provided to NBC News and CNBC show that several sports organizations had accused the accounts of violating its copyright protections.
Among the organizations filing the requests were the National Football League, the Big 12 and Southeastern collegiate sports conferences and Ultimate Fighting Championship.
Both accounts — Deadspin's main account, at @Deadspin, and @SBNationGIF, under which SBNation often publishes short GIF clips from sports events — suddenly disappeared Monday afternoon, replaced with a notice that they'd been suspended. @Deadspin had been restored by late Monday night, but @SBNationGIF remained unavailable early Tuesday.
A Twitter representative said the company doesn't comment on individual accounts.
