Just like a crazy tattoo you get when you're young, the images teens post online can stay with them forever. "Deleting" a photo will never get rid of the embarrassing pic completely, so when these kids get older, they'll never know what a curious future employer or college admissions officer will come across.
I guess these oversharing teens just have to hope that the people deciding their futures also have embarrassing photos of themselves floating around on the Internet. And judging by this survey, it won't be long until many do . . . we just have to wait for today's teens to grow up and become the employers and admissions officers!
