and that's sort of how this all evolved for me. i became aware that morgan essentially had a separate identity. all online that i wasn't aware of. >> a secret online identity hidden from parents. this is the dark side of the internet. many teens now have multiple online accounts, a public one and a private one for a select group of people. they exist across platforms. facebook, tumblr, twitter. but they're most common on instagram where they're known as finstas or fake instagrams. and while it's called fake don't be thrown. what kids post there can often be more real than their public accounts.
