It's a finite reach but that finite is FAAAAAAAAAAAAR for some chicks. For some it isn't. There's still a ton of untapped talent in the world: I've posted in other threads and even created others for a particular French stripper I follow who I think would SMASH it in porn but she'll probably never make that jump.
Nadine got famous REALLY quick in Germany and as a result, most of Europe. Took a minute for the US and the rest of America and STILL not a lot of people know about her, but she's definitely made a mark. Not a big one: you do have to be really deep into her fandom, Dredd's or MoneyBirdette to know, but again: Europe is her bread and butter. And Germans are NOT afraid to go batshit nasty: Dolly Dyson, Cara Mella, her, Jolee Love, it's ENDLESS.
