Hot chick I knew from primary school class 10 yrs ago liked me on tinder (i didnt recognize I know her). We had talk then I left the app (dont wanna have contact with anything from that long ago lolo) Then i wrote 3 first letters of her first name on Facebook (in search in the topbar) and she was first. 0 common friends. Why? Answer is simple Because she looked me first. Theres no other reason. she shouldnt appear as I didnt write her full name not even first name. And no common friends so. So why she appeared first? Obvious I made that thread long ago but nobody gave a F. I was unsure but now I have confirmation. PS you wont see it if you use facebook too often. Only if you dont really search anyone.
