Distributors like Distrokid, Tunecore, CD Baby, and Awal all have to pay you royalties. You think they’re not going to develop technology to protect their business from people who are trying to game the system on streaming revenue?
Fake plays give fake profits to an artist that haven’t been really earned. Companies like Spotify and Soundcloud don’t want to have to give money out to people who don’t earn it and distributors will drop clients that do this in order to keep a strong working relationships with these websites.
Despite what you think, it is very easy for professional companies to spot accounts that purchase views, plays, and likes. They will pass over accounts that they feel are fake when looking at new talent and stick with the more organic accounts. There is no retention in these plays. Once the person who has been paid to check out your account has finished the task, they move onto the next client. You want real fans that are going to continually come back as a way to check out your music.
Retaining fans is a more important aspect of growing your career than just getting boosts that are temporary. You may not get as much of a return on your investment as you think you would, which is just another reason why you should avoid buying cheap or fake plays.
