Are you really sure? I look at a page and I see the same postings by the same people every single day of the week....are they really coughing up $5 for everyone of those? Maybe it's a real escort, but I'd still consider repeating postings to be spam that ruins site usability (since it pushes everyone else's listing down to the bottom of the page, and encourages them to spam as well).
It doesn't explicitly say it, but the gist I got from the article was that fees were instituted last November, but it was mainly just for the purpose of identity verification. Which meant you paid a one-time fee, provided a phone number and credit card, and could then spam to your heart's content.
It sounds like the new system has you paying for every single listing and every single re-listing, because they need to pay a team of people to screen these ads. How would you like that job?

Sitting around all day, looking at tits and ass and cheeseburger cocks....and somehow getting paid for it.
OLD:
Under pressure from 40 U.S. attorneys general, the site agreed in November to charge people posting erotic ads $5-$10 by credit card and require them to submit a working phone number to use the site.NEW(?):
Postings to the new section, which opened immediately, cost $10. Once they are approved, they will be eligible for reposting at $5.
