Anecdotal evidence, but have a look at the public gallery pic of AW Maggie "oily ass", where she's looking into the mirror.
The pattern of that tattoo on her (Maggie's) left breast looks very similar to Mercedes's left breast via the agency link.
I was a bit cryptic, Andy; I know what you're saying. I meant to imply, don't take too much notice of their AW profiles or feedback. They're probably perfectly ok girls, but booking them is virtually the same as booking them through one of their agencies. Some ex-agency Thais have gone 'indie'. You can usually spot them because their profiles are much more 'vanilla'. These girls, all of them, will have someone else answering their emails, because their English isn't up to it, so when you get there they might not know what the hell you're on about. In another thread I've posted some TG's who are totally legit, but they tend to move around the country. Suzi Li is, however, an exception to that.
