One agency, mentioned as verified, asked for copy of government ID card and bank account number! This is very suspicious. How do you certify ads as "verified" ? And, what is the difference between verified and unverified ads?

Hi, We request our user to send us a photo with the person holding a piece of paper with a special number we provide, then we compare the person in the photo with the photos on the listing and if they look like the same person we mark your photos as verified.
Thanks, Claire.
