Is it just blocking? Without forcing people to unfollow?
Clicking ignore again puts them back in followers list.
They can watch, they just can't favorite, or submit comments. It just stops them from interacting. You have to full on block them if you want them to stop watching your posts.
Actually, I appear to have brain farted. There is no blocking, there is just ignoring. My apologies.

If you ignore people, it means that they no longer have permission to comment, or favorite what ever it is that you post.
