@evan I'd say no. I don't want to know if I've been blocked. I'm not for everyone and i know that, but if I'm not for you, I don't need to know about it. Just block and move on. It's not like the other person can stop you from blocking them anyway, so just do it and don't be passive aggressive. I might tell someone else "Oh I have that person blocked," but never directly saying to that person "I am blocking you."
