I'm w/ Galleria on this one. I have varies ways & considerations when screening. I lookk at your post history, the way your encounters are worded, etc, reverse search phone numbers being used, search lists, etc -I do all this while texting (as I refuse to talk on the phone -to be able to screen & multitask is one of the reasons why). If everything is syncing up while I'm texting & what your saying is matching -sometimes, my dates don't even realize that I've screened them & have been screening them while texting. I've had to explain this a couple times to people that ask when they arrive & they laugh at how subtle & painless it was. Lol
between reverse phone number searches, provider lists, apps, post history, encounter history, or references (Do I know the reference well even maybe) , -there's def subtle ways.
Now newbies that's a dif story -then they need to be more understanding that they are gonna have to cooperate on more thorough screening
