How would you handle this situation if you had a sibling like that?

I have a married sister and she had became very nosey in my things. I dont to dhat to her but she feels she has the right to do it with me. That os why I blocked her from my Facebook account from my contact list like 2 months ago, because she is very Facebook fan and post things and she likes if other people do it to. When I had her as par tof my contacts, she likes to question me for everything I post in news feed or any other feed we had in common. If I commetned something about any news there was a possibility she may read my comment and if my comment was bad or a bad joke, she in private questioned me why the heck I posted what I posted. I mean she liked to pursue me I mean I could not have the freedom to post anything cause I was always afraid she may read what I post and then tell me something about it.

That all ended when Iblocked her from my contact list. But today as it was my birthday, she took some photos of me singing HB at home and she (without asking me if I want) told me she was going to post the photos on FB. I mean I dont mind that much if she posted them or not, but she automatically took the photo to the reason to upload it so everyone knew it was my birthday. But since I did not have her anymore as my contact list on FB she could not do it. But then she asked me "Are you on FB? I thought you were on FB, I want to tag you in the photo. Why dont you check what happened to your account because I could see other people wish you Birthday? So now she wants me to add her again so she can post the photo.

She never knew I blocked her from my FB list, as maybe she never noticed, but today as she ask me to post the photos on FB she asked me what the heck happened to my account. I told her a fiblet about something that happened to my account She even ask her husbadn to

help her find out why she could not see me and texted me in private that now she knew the rason and she told me "You blocked me". I mean you see, that is the exact reason I blocked her in the first place: She nags a lot and question my moves on FB. Now I will have to add her again so she post the photos becaus she wants to post the photos on FB of me singing HB. Once again I won't have the freedom to comment on news feed like I was after I blocked her cause in any moment she could read where
