In the "real world" a while back, I was dating on one of the mainstream sites and used my screening skills learned as a provider and stepped it up a notch or two.
Because I am not someone who could work as a provider while dating someone exclusively - and dating someone exclusively was my desire at the time - there was an opportunity cost involved in dating someone. Therefore, lifestyle mattered. I would be giving up a lot to date someone; I wanted it all or not at all.
For every 100 inquires, I went out with approx 3-5 men. This part was screened on basic compatibility. Did I like his style of communication, did he want more children (no thank you!), etc. Once we got past that and self selected to a low 3-5%, I would do my research.
One time, I met someone for wine and appetizers and I knew this about him going into it: His last home was 4 hrs away with his not quite ex wife. they rented and the house was under $200,000. No children, I knew the make of his car (and his not quite ex's) and that they both owed balances on both of their mid level vehicles. He currently lived with a relative in Houston. No past divorces and no civil/criminal convictions. While it wasn't the lifestyle I ultimately want, I was really intruiged by his involvement with a certain poker website I play on regularly and thought that there was growth potential and mutual interest.
Over wine, he talked about how he left his ex wife (said they were divorced) everything - a $500,000 house and a paid for 6 series convertible. I quickly ended the date. I may not mind 'em poor but don't lie to me
I found all that out on a site I pay $25 a year for and open records on government sites, using only his name and general age range. And if I ever go on sites like that again - though my current paramour makes it extremely difficult to consider anything of the sort, as my life is so comfortable and happy now - if I did, I would screen the exact same way.
Before you go and get all excited about your risk as a client - #1, I'm extremely good at data collection. Not everyone can do what I do as well or as efficiently. #2, I never did all that background on someone who was a client because it doesn't matter. The things you look for with a client are: am I safe? and can he afford the cost of entry? So don't get all excited about girls having access to your name because most can't do it and the ones that are smart enough to do it don't care.
