Hey @Wolfer - there are still a sizable number of reviews on Daddy's. You might also try searching for the escort's name in the Deli Forum here. I often scan the escort's ad reviews for client names that look like trusted Forum members. A few times, I've messaged other clients directly asking if they could share more information. For a general question to the Forum, you may have noticed "411" threads asking for feedback about a specific provider. It's best to search first, though, in case someone else already posted the question.
Without being too much of a stalker, I use Google reverse image searches to help verify if the escort is real. And it may help to search by phone number to see if anything suspicious pops up, such as multiple escort profiles with the same number.
My own common-sense approach uses four criteria: good escort ad with no red flags, some positive feedback on the Forum or Daddy's, the escort responds well when contacted, and my intuition. I need three of those to feel good about meeting a new escort.
