Has anyone tried meeting anyone off ‘Tryst” that was not already reviewed on TER?  
What are some red flags or things i should watch out for?

On Tryst, put in Saint Louis as your city. Then, in the search options, find "keywords" and put in "TER" in that box and clock "search." Several attractive women with TER reviews showed when I did that. I didn't look at the reviews but you cant take it from there.

You can use their email to search for reviews.  

I have seen a couple girls off Tryst without reviews but you have to be careful.  
Lots of fakes out there, there is no real way to know but if they are a traveler and have no other ads on quality sites (TS4R, TSE or Eros) or reviews I tend to stay away especially if all of their pics look like they were all pro photo shoots.  I have seen a few locals (my city or a city I am visiting) and I have not had any issues.  Just gotta be smart and listen to your big head, not the little one between your legs.

Appreciate your responses 😊

Eros is considered quality? I assumed they were of the same risk as tryst

I search for email / name in TER,  
Filter for keyword “TER”, “erotic” in tryst
Google any combination of email / name / phone number” etc with “erotic review”
I slosh check p411 to see if I can get any info there as well.
