1. Women in the industry will lie right to their fans faces and say they're not escorting when they're listed on the front page of an escort website. So asking them if they're available isn't always the best course of action.
2. Eddie has been wrong at least once about a very well known, yet UTR, woman in the industry.
3. Photogirls has had questionable behavior in the past, I say questionable because in the past they have been known to pull a bait and switch with some of their women. So with that caveat out of the way, the only way to be sure Eva is actually available is to check around.
4. The big name adult stars on photogirls are also available (except Eva) on Alluring-escorts, which is a pretty reliable agency. So you can check with them if you're interested.
I've been wrong more than once, I'm sure. That's why you'll ususally see my say "I don't BELIEVE she's available". When I say I don't believe a certain girl is available, it's based on the information I have, which not to brag, is pretty extensive. So if the girl in question isn't on any of the VIP sections of an agency and I haven't heard her name mentioned by industry people I know who are privy to these things, then my assumption is that she's probably not in play.
But also remember that a girl who wasn't available last week might be now. The downturn in the adult industry has made escorting a more attractive "side-job" to women who are working 1/3 as much as they were last year.
Personally, I believe that just about every pornstar is available at the right time, the right place, and the right price.
