Ok it's because there is a "porn world." And the problem is, it's all these detached and jaded men who don't know what true porn fans like to jack off to.
Me personally, a nice ass, natural C cup or larger tits, a vagina that doesn't look like an arby's sandwich and decent face, is what I look for physically in any woman. However, to really dig a scene the chick has to be energetic and perverted.
Chicks are insecure about their tits like dudes are about their cocks. So superficial Los Angeles pimp parasites (AKA Derek Hay) coerce these chicks into getting hacked up tit jobs, or they are told by some 50 yr old director for Hustler that they need a fake rack.
These people don't know the current trends, they still think Savanna was amazing. If more chicks had nice looking tit jobs like chicks in the 90's then it would be cool. Unfortunately if you go to the LA Direct website you can see the ugly butchered tit jobs all over the site. Gianna Lynn has a fucking disfiguring tit job, and so does that ugly alt chick reeegan reese.
