How trustworthy is "Eros Verified" (i.e. what does it truly mean)? My understanding is that it verifies the face on your pictures is you, and you're over 18, is that right?

(For context: Provider who was Eros verified seemed amazing, but had no online presence and reverse Google Image showed someone must have cropped her face on someone else's body from other source. She only did outcall and wouldn't do video confirmation, yet doesn't require a deposit. So if she's Eros verified can I assume someone with her face really did sign up for it? I don't understand what the catch would be)

The short answer is no, you can't trust the ads to be accurate or even real.   I don't know if you are new to this or only new here, but look for ladies that have a good online presence or are well reviewed.  

To be verified by Eros, one must: "Upload a verification photo, which is a clear face picture with the model holding a handwritten sign that shows the date (MM/DD/YY) and the word Eros written on it."

The verification process is not only irrelevant but also fails to provide meaningful insight into the model’s legitimacy. By focusing on this feeble form of verification, we detract from the critical analysis needed to truly assess the core concerns of the model’s authenticity.

In 2017, the Feds raided the US offices of EROS. They hauled away boxes and boxes of info. EROS was down for around one day and then back on line as if nothing happened. There has been a lot of speculation that the FBI might try (did try? has tried? is trying? will try?) to pressure Providers to assist LE in some circumstances.

So far, I don't think any such cases have been reported but I'm not sure how we would hear about it anyway. From a Provider? "Hi, I just helped LE bust a couple of guys but don't worry. They sealed my records in exchange for the help so my record is clean and I'm back in biz! Come and see me. Send a photo of your driver's license to me at ..."

They are not to be trusted. I got ripped off in a scam by two fake providers years ago. I complained to Eros because they were "verified" and they basically told me that "verified" doesn't mean that they aren't a fraud.
