Puzzeled...

This is a question for all of you who've been here for longer than I have. What is it with all the advertisement accounts - accounts clearly made to promote a business, no posts, no followers, that have nothing to do with the purpose of this platform? It is a mystery for me... Why would someone expect I would be interested in doing a laser removal located in DUBAI when I live halfway across the globe, and that I would choose them from a platform destined for writers? Are these fake accounts? What's up with that? Why waste time? Just... why???
