If you denied it-why?
Did the person ever ask you why?
Yes, I have denied people that try to add me from High School that I don't even know who they are. We also denied and blocked DH's sister's sister...she's a whackjob and disowned us years ago but now wants to add everyone and be nosey, yet still will not speak to us. I've also deleted my FIL b/c he never even "spoke" to me; he just wants to be nosey and all up in my business, so I removed him from my friends list. If he noticed that I did it, he hasn't said anything to DH about it.
I've never gotten any emails asking why I didn't approve them or why I deleted them. I honestly don't think the person even knows.
Can you tell me how to remove an existing friend? Can you block them and they "think" that you are still friends?
I've ignored a few friend requests from people that I don't recognize. The only way that anyone would ever know that you ignored them is if they went back to check to see if you accepted them. When they click on your profile and you haven't accepted or ignored them yet, it says "awaiting friend confirmation" by your name on the page. If you've ignored them, they I believe it doesn't say anything at all, so they know that you've ignored them. I have some friends that don't click either accept or ignore b/c they don't want to be rude, so the people are basically "awaiting friend confirmation" forever.
