To my knowledge, you invite them with the social media account with which you are connected. For instance, if you look up black_dragonet in Facebook and add him as a friend, you and I will become linked. Then you will see my TT times (WTT and career TTs) in the middle part of the section.

I would guess that if you unfriend him, he disappears from your list. Since this happens to not be my real name and I quite like to have more references to compare with, I would agree to add whoever from this forum asks me as a facebook friend.
