Endorsement

In 2019, the FTC started to crack down on Instagram influencers who were not disclosing which of their posts were sponsored. Do you think influencers should have to disclose which posts are sponsored or not? Have you ever been unsure about an endorsement (Instagram, podcast ad, radio ad, etc), not knowing whether it was sponsored? If a consumer were to discover that an influencer was indeed sponsored, in what stage of the purchase process do think effectiveness might be most affected? Why?
