Some girls will try anything just to have a good looking Instagram profile and they will start beautifying their profile by posting their photos. But their problem is that, even though they post nice photos, they do not get that much attention like getting Instagram photo likes.
So they will start searching for how to have many Instagram followers on Google. They will click all the website listed in the search results because they think they are all real.
If you are really serious about having massive Instagram followers and promote yourself to become a model or even promote your business then you may consider buying Instagram followers, just be careful buying followers to websites that say they offer real followers, not bots.
Because some websites are selling bot-created Instagram followers, meaning those people that will follow you are not real people. Because of that, you will waste your money because those followers will not be active and will not be commenting or liking your photos.
You may use them to make your Instagram profile look good though because having massive followers on Instagram will make people think that you are kind of popular.
