The minute I see the word 'Goddess' on a profile I almost know it means a shite punt. There were a few other red flags which people have picked up - limited 'likes' for example.
To be fair, however crudely they might have phrased it, I'm not convinced the posters are out to be racist at all. There is a solid body of factual evidence on here that suggests many (but by no means all) of the Romanian girls deliver very poor service; the ones concerned are almost certainly pimped - whether they are 'trafficked' or not probably depends on your definition of that word. They are undoubtedly part of a shady, criminal sub culture and who knows whether they have a coercive relationship with Sergei. It would certainly explain their generally sullen demeanour and shite service. I don't see it as racism to say that.
There are, by contrast, other Romanian girls who are independent and don't come into this category, and provide an excellent service.
It might be too early to say, but a similar pattern is beginning to be set by some of the black girls on AW - again, I don't see it as racism to say that.
