Copyright laws are a complex beast. One person's fair use is a content owner's reason to shoot off a DMCA takedown notice. Gawker Media's sports site, Deadspin and Vox Media's SBNation both found that out today when their Twitter accounts were suspended after continuing to post GIFs of NFL-owned content. The @Deadspin account has since be reinstated while SB Nation's account (@SBnationGIF) is still unavailable. Gawker Media executive editor Lacey Donohue confirmed via Twitter that the notice concerning the suspension from the social media site was from the NFL. Earlier reports indicated that MLB was also involved, but that turned out to be untrue.
