One of the real insidious problems with Instagram and to some extent Facebook is that they provide a free, low friction way for business to communicate with current or potential customers. As a result many small businesses use Instagram as replacement for a public facing website and perhaps a blog or email newsletter. Many small business in my region depend on Instagram for this purpose, its nearly universal. It helps keep you stuck in Instagram so that you can see a business' hours, menu, or special events. I guess a shell account is the answer but you're still going to have to navigate the skinner box feed.
