Twitter is cracking down on digital media properties that publish highlights of football games on Twitter without permission.

Twitter temporarily suspended the main account run by Gawker Media’s Deadspin sports site, which had been sharing GIF and video highlights of NFL games.

Over the weekend, Twitter also suspended an account, @SBNationGIF, run by Vox Media-owned SB Nation* for posting GIFs of college football highlights. It has yet to be reactivated.
