How tf do foriegners find me on facebook/!?!?

[aintnobodygottimeforthat!]

Fooreals tho .
When i first made my facebook , like i didnt even put up a profile picture yet.i only had it for like 3 mins and a middle eastern guy messaged me tellibg me stuff and when i asked whwr ge lived he said "far far away" then blocked me .
Also when my sister made her fb the part wher it says "_____made a facebook" some indian dude liked it. She didnt even have friends yet. Si my question is how do they find us???(americans)

they are friends with someone you added as a friend, or are members or a page or group you are a part of.... you get suggested to them as a possible friend
