What exactly do you think it subscribed you to? When you logged into Smedian, it was clear that you were logging into PenName, a single platform in which Smedian is a part of. You only have a single profile across the entire platform. What you may be referring to is the fact that I have new users of the platform follow me on ManyStories and Writtens. This is purely to create awareness for new users. You aren’t subscribed to anything at all.
I hope this clears things up for you.
