it is about as real as a 3 dollar bill
It's fake...that much quoted Maxim story? It was written by Joe Zigfield, someone who works in the adult industry...yes he might've indeed fucked Brittney Skye, but he wasn't recruited as a member of the site, that's for sure. The Maxim story is, charitably, 80% fiction. Google "Joe Zigfield" and you'll see.
The fat folks/normal looking folks you might bump into on the site? You guessed it, all affiliates with the adult industry. Maybe it's the site owner's brother, some camerman, who knows.
As for the folks paying $20/month thinking that'll give them a chance with the likes of Brittney Skye...good luck, you'll have better chance winning the powerball. Though if you want to save up, she's only $3k/hr according to bella models anyway.
