I definitely look at posting history, who the guy has reviewed.
There are some ladies that I trust more than others. If I don't know anything about the lady given as a reference, I may ask for multiple references or ask the ladies that have been reviewed. I try to answer reference requests in a timely fashion so the guy can set that appt quicker.
I am also newbie friendly and have alternate screening which I won't get into.
There is one lady that asks the guys to send her a photo of themselves taken that day with something specific that lets her know it was that day.
It does seem like there are a few guys that like to find a way around screening. They will email ladies claiming to be a prominent hobbyist and some ladies just accept that. They may also say they are someone that we have seen before. But with the 3 major threats in this area, we all have to be more diligent to remain safe. (I'm sure there are more than 3, though)
