I've said before on these threads that it very much is like an MLM scheme, in order to make any money they need people to follow them.
In order to get free stuff they need to convince advertisers/brands that they are a cheap and efficient advert, because for these big brands this is very cheap. They just supply the product without needing to pay for a pricey ad campaign or loads of ads, they have the instamums to post, blog and vlog and go on and on about their various tat and it's all being consumed by their target market or more realistically, those who aspire to be their target market.
When you try and flog yourself as a product, like a lifestyle you can pull from a shelf, look how happy I am you can have it too by buying this junpee, toaster etc etc or you can post about it, it's 'mumpreners'! Women couldn't possibly exploit other women, it's an insta family you know, people either love them or are envious, there is no middle ground or grey area. But don't worry, they take your concerns into consideration, a very heartfelt post about listening and being honest will follow as will the avalanche of oh huns you're so real, please don't listen to the negative bullys, I'm so glad you wrote this it's now acceptable, no scrap that, it's your duty to flog shit at me, how could I have ever doubted you. Nobody looking sad in a jumper could be dishonest.
