Some do. My girlfriend has purchased clothing after seeing an influencer's post on Instagram. Granted, she has to REALLY like the piece of clothing to buy it.

Regardless, it's infuriating to read hotels, airlines, clothing companies and others throwing money and freebies at people just because they have a high follower count. It's also sad to watch people from my hometown become walking advertisements -- one girl recently started shilling for Disney -- and try pushing their "brand."
