lol~ necrothreadbumping D:<
btw, i hate kssn stealers, but i'll just answer your question anyways -
the first 6 digits in the kssn you see is the birthday in the order of [year/month/day].
so for example, it's the number is 870307, that means the person was born on march 7, 1987.
so do the math and since it seems like you're doing it the illegal way, find a kssn that is under 18~

sorryifthisisconsideredkssnconversationbutitshould n'tbe:x~

not encouraging people to use other people's kssn, but i'm just generalizing what a kssn consists of,
there is no info whatsoever on how to obtain a kssn etc ;0~
