It's seems more the failure of critical reasoning and resilience amongst many people. It ought to be possible to be bombarded by messages and do a cynical yeah, whatever and to a degree that's a learned skill that it seems people increasingly aren't learning. The world is full of people who are more attractive, richer, slimmer, taller, etc. and yeah, social media will expose users to that, along with whatever they want to sell as part of their influencing package. But I don't think it can be wished away or somehow banned – people have to learn to deal with it.
