While I personally have not met "Angel", I do scan the various Portland sites frequently.  You might be interested to know that "Angel" on the Portland Adult Entertainment Guide site also advertises herself as both "Jordan" and "Autum" on the Portland Exotics site, using different phone numbers.  I also found the same situation with another provider who looked hot, "Traci" on P.A.E.G, advertising herself as "Jenny" on PDX Exotics, also using different phone numbers.

While this may signify nothing more than a provider using different names and/or phones to see which ad works, I myself would stay away from any advertised provider from those sites.  I refer you to the Portland TER page, and the recent reviews of Evette and Shannon, who can both be found on PDX Exotics, and both were real rip-offs.  These sites, and others like them, seem to have more than their share of scammers and providers who promise F/S on the phone, and then take your $$$ without "providing" much at all!  

I would consider a provider "legitimate" only if she at least had her own web page and reviews, and not be featured in these "erotic marketplace" pages.
