Reply to Soundcloud follow spam?

Hey,

I was just wondering about all these accounts with 2k followers. I get spammed everyday by people following and then removing the follow.

Is this some sort of bot? If so I don't understand what they could gain from following, and then removing the follow after a short period of time. The only thing I could come up with is that they want to abuse the email I receive saying "X has started follow you", "If you want to get updates on X tracks and comments you can start following X too".

Have I missed something here, or is it simply abuse from some random bot?
