We all know what Hustler is. And if you're a gormless startup founder picking that as a name for your app or product, well that's your fault, learn you some history and watch "The People vs Larry Flint"[0]. Flint's case in the Supreme Court was hugely important, despite being a "purveyor of filth", and strengthened free speech rights in the US, in particular Hustler Magazine vs Jerry Falwell[1].
