In response to 3. I'd argue it's a much bigger factor than we'd think. Instagram as a platform is now based almost entirely around influencers creating an idealised and unattainable representation of a lifestyle and then selling ad space for your product to be seen as part of that lifestyle. All social media enables/encourages this to a certain degree and I think the personal touch and reach that individuals give to the products they promote is potentially far more subtle and harmful than the banner ads we typically think of as problematic.
