At the time, Brittany was listed as one of TIME magazine’s 30 Most Influential People on the Internet. But before she was a Vine star, she describes herself as “really shy.”

“I was like, the little kid that hid behind their mother or their father’s leg,” she said.

But making Vines changed her into a person she didn’t recognize. “I don’t know what happened — I just became this monster who constantly wanted to perform,” she said. But after her peak, her numbers began to dwindle.

“I left Vine because Vine got more toxic for me than it did positive,” she said about her plateau in followers. It was then that she made the decision to leave the app, before its eventual end in 2015.
