The whole reference/newbie/p411 ect. thing has been discussed and beaten to death.
First, there is nothing inherently wrong with Backpage. Some of the more highly recommended escorts on TER advertise there and have for years. But, of course, there are bad apples as well. I think it is important to read the TER review section about particular providers, rather than just lump them all together as backpage baddies.
If you see someone on Backpage that you think you might enjoy, and she has reasonable TER reviews, more than likely you can see her with just a phone call.
If you want to jump through the hoops with the "need reference" group, then it is going to be difficult to see them. But, those few who require references, though they may be very prominent here on TER, are among the minority in the escort world.
I have no experience with the p411 type businesses, but I am pretty sure that I am not going to give out my exact and true particulars to an on-line group that is aiding me to perpetrate an illegal act. That, in my opinion, is thinking with the wrong head.
Remember, what is put into a computer data base stays there forever. But, then I suppose if you are not planning a career with The Secret Service it might work for you....
