You get a feel for the fake ones after a while, it is very obvious. I think if asian is your scene you are better off trying proper establishments. For caucasians, you can do an image search to see if the images are fake. Other good tells that they are real is if they have a twitter account which has been active a long time, or have an onlyfans account with lots of likes and has been active. Also, if it is anything under $400 an hour you need to be sceptical if they look really hot. If it's too good to be true, it usually is. Not saying you can't find some diamonds under that price but it's much more unlikely.
