Twitter on Monday suspended two high-profile accounts that post highlights of sporting events, after several major sports leagues complained.

The suspensions of @Deadspin, the account for a sports blog owned by Gawker Media, and @SBNationGIF, an account for the Vox-owned SB Nation website, brought to the fore an ongoing dispute over whether the highlights are fair game for publishers.

Using GIF animations and Vines, which are six-second looping videos, the two Twitter accounts react quickly during games to bring their hundreds of thousands of followers key plays and bloopers.

Agencies representing the N.F.L. and Ultimate Fighting Championship filed complaints against Deadspin, according to Twitter. Takedown notices against SB Nation were filed on behalf of two major college football conferences, the Big 12 and SEC.
