I am not sure it is possible to clear a certain nickname from the owner. Besides, why borrow someone else's username when you can create your unique one and promote some product. It seems to me that it is much more interesting and profitable. I recently registered on Instagram, but I've already tried
buying real instagram followers. I felt the effect of audience growth and realized that I wanted to develop my blog. As a result, few people were interested in how my nickname was recorded; most people watched and evaluated the content. By the way, how do you like the idea of sharing pages on Instagram?
