Thanks for the mention! The stories in your publications should reach readers if writers are using tags relevant to the stories. But your suggestion may help, if people check those tags frequently. They could equally just visit the publication and read from there, of course.
As I said yesterday when you raised this, there is no reason why writers cannot unfollow publications. I write for Illumination, but I unfollowed them recently because of exactly this problem. I'm still a writer for them. It doesn’t result in expulsion.
I hope your idea helps!
