The US anti escort movement has been under way for some years. It's definitely not recent. There used to be a great site, (reviews, ads, chat forums) "My Red Book" , mostly dealing with Bay Area escorts, but it was closed down about 4 or 5 yrs ago apparently for tax reasons. I was sure another site would soon spring up to fill the gap as Red Book was very popular but, as far as I know, nothing has. Then Craigs List and Backpage became less escort friendly. "TNA Board" is a site that seems to have legit reviews and ads but it's main focus is Oregon and Washington.
Punting in US is now pricey and potentially hazardous (ripoffs, cops) so I wouldn't recommend it. Canada seems to be just as pricey but has a healthier attitude.
