What are the rules / law for identifying an instagram post as an ad? If this isn't enforceable then young people don't stand a chance against the insidious nature of marketing. In the 90's, "cool-hunters" would hire street promoters to hype brands one-on-one, directly to the consumer. These promoters were often friends of the consumers, who essentially became walking adverts for <insert big brand here>. Sounds a bit like the company "Influenceter". It's always been a goal of advertising to capture the minds of the youth culture. Facebook just does it to scale.
