Nothing new there.  It happens often.

I will say, it does not happen so much on ERO* as it does on sites with lesser reputations.

This is very common and it's either a scam or a touring lady trying to drum up interest in potential cities. Honestly, though, I've found that Eros has become unreliable as a source for new providers. Large numbers of posts have no other Internet presence other than the ad and then have very stringent and revealing verification procedures or electronic deposit requirements.  I'm happy to verify and/or make a deposit if I can find a website, reviews, a Twitter account, or a reputable booking agency associated with the provider that lends legitimacy to the ad.  

Scamming is a big business on the internet. You gotta keep your wits about you and think with your big brain.
