(Yahoo!) - To each his own cause.

While Bruce Willis was busy debuting his new baby girl, Evelyn, on Instagram, one of the actor's other four daughters, Scout, was busy taking a stand against the social media platform. Specifically, its nudity clause.

The 22-year-old has been walking around New York City topless in protest of Instagram taking down some of her photos, which violate its Community Guidelines.

It apparently all started when she shared a pic of a sweatshirt she designed called "The Babe Bomber," which features an image of two topless women.  When Instagram removed the shot, Demi Moore's middle daughter responded on Twitter: "Well f--k you Instagram #RIP."

She's been on a rampage ever since and reportedly even changed her Instagram name to "Scout (Areola) Willis" — before her account was deleted.

"Legal in NYC, but not on @Instagram," she tweeted on Tuesday along with a topless photo of herself shopping for flowers in NYC.

Maybe Scout should ring up Rihanna for some Instagram venting?
