Snapchat question?

Recently I havnt been on snapchat bc I don't know I just don't want to and I had issues with it, with my ex but anyway I deleted all my friends and at one point my only friend was my ex but since I don't go on it I deleted him and also blocked him but I keep getting these random quick add people and they are all girls and I don't know any of them, and when I look up quick add how you get them it says I have to "are based on who you're already friends with, who you subscribe to, and other factors." Sooo since my ex was my only friend at one point is that his friends? Or people he talks to?
