This question already has an answer here:
I want that even if my friends have activated "Get notifications" for me, stop them from getting my notifications because I don't want my friends from seeing my likes, comments and so.
I have seen How do I stop friends from getting notifications about what I do on Facebook? and my question is right that.
But unfortunately it has been marked as duplicate with a totally different question (Turn off close Facebook friend notification) while they differ.
