I reckon you're right, look at the URL for the first one, it has 'jesy' in it, 2nd profile is called jesyca. probably hungarian, maybe rom I reckon at that price.
Which probably means all the pics are fake, also green ticks to the whole likes list is usually a sergei in control, you can find some gems but they are few and far between on Viva.
Until recently you could see all the ads by a poster, it gave the game away, and meant you could find those genuine ones, they normally only had 1 post, 2 if they were close to another area, but both ads would be exactly the same, shame they removed the feature.
