I really love you, man, so I'm going to be tough on you.
"Providers, please be honest"? Really? Who are you talking to? Do you believe that the creatures you are referring to read these pages?
Anybody with a couple of bucks and a debit card can place an ad on backpage. If a girl knows she is not hot enough to attract any clients, she will find pictures of a hot girl on the internet and post it. She calculates that most men are too stupid, too scared, or too horny to walk away (but if a guy DOES walk away, what has she lost?) Any girl who wants to run a real scam - cash and dash, or worse - do you harm, is sure as hell not going to post real pictures of herself.
Now you've already received a number of responses telling you not to use backpage, and that is good advice for any relative newbie. You are already a member here. Pay for VIP, search for the type of providers you want, read the reviews, and BANG! You'll be a happy couple MOST of the time.
You can't go to the dollar store and complain about the quality of the items. There are bargains at the dollar store, but you have to do your homework and be an expert shopper to find them.
