Instagram is a very good idea but in my view it’s overprotective of its advertisers. An example. There are numerous advertisers on the website that claim to have the solution to male baldness who market the most unlikely of solutions at a very premium price. They all have a page where you can leave comments. If you do as I have and leave a explanation as to why their product is unlikely to work this is deleted and Instagram suspended you from posting anything for a few days as has happened to me on several occasions So when the uninitiated read the products many positive comments they tend to look favourably on it. This is known as cherry picking.
