"I still haven't found one leggit provider on there, almost as bad as backpage"
Really???
I don't understand how a question about the level of activity on ECCIE results in badmouthing Vegas providers. How one would even equate Eros with BP is beyond me. The minimum amount to advertise as an escort on Eros is $150. A BP ad can be purchased for a mere $12. Opposite ends of the spectrum.
Now, there are 48 ladies in the VIP Escorts section on Eros Las Vegas, and more than half of them are reputable & reviewed. Many mention being reviewed in their ad headlines or in the actual ads. All you have to do is google any working lady's name/email address/phone number to find her reviews.
I advertise on Eros, as well. There are thousands of escorts in Vegas & hundreds of them are reviewed. So, if you can't find quality here in Vegas, specifically on Eros, it's not because it doesn't exist. It's because you aren't looking hard enough. Just my thoughts...
