On April 19, 2017, the Federal Trade Commission issued warnings to more than 90 brands and “influencers” that their social media posts should more clearly and conspicuously disclose brand connections. The warning letters follow petitions filed by consumer advocacy groups aimed at influencer advertising on Instagram. The FTC’s warning letters show that the agency is committed to capitalizing on its recent enforcement actions against brands and influencers, and will continue to scrutinize social media compliance with the Endorsement Guides.
