Here's my observation with EROS ads, especially ones like the OP posted. There's no descriptive bio on the lady, as in other ads. Also, the other web presence she has is on the 'models-world' page which seems to me like a site I would not trust. Also, no reviews show up either here or on TER that I see. No ad on tryst or any other reputable site. Someone is placing the ad for her.
Just think with the big head instead of the little one. Despite her looks, I would pass since the spidey senses are telling me to stay away...
