While AmateursRaw could be referring to the fact that the guys dont wear condoms when they fuck, I think instead it is meant to indicate that these babes arent all that polished on camera. That isnt to say they dont look good - cause they sure as hell do. But its more the fact that many of them havent been on camera much before, if at all (or at least thats what they claim).
Each of the 71 videos I checked out began with a little interview between our amateur and the guy she is going to fuck. He asks all the basic questions (what she has done, what she likes, is she nervous, etc.) and then gets her naked. This leads to the pussy play, the cock-sucking, the fucking and the facial cum load.
