Amazon should be subject to the same disclosure requirement, which would negate the value of the tweets, which may remove the need for their employees to be put into this position.

> The FTC’s Endorsement Guides provide that if there is a “material connection” between an endorser and an advertiser – in other words, a connection that might affect the weight or credibility that consumers give the endorsement – that connection should be clearly and conspicuously disclosed, unless it is already clear from the context of the communication. A material connection could be a business or family relationship, monetary payment, or the gift of a free product. Importantly, the Endorsement Guides apply to both marketers and endorsers ... consumers viewing Instagram posts on mobile devices typically see only the first three lines of a longer post unless they click “more,” which many may not do. The staff’s letters informed recipients that when making endorsements on Instagram, they should disclose any material connection above the “more” button.
