I'm surprised this didn't come up earlier, but yes, 4 Thai houses in OC were busted as part of a trafficking related sting. Thai Angels ran two apartments and Asian Food Network ran two apartments in OC and one in San Diego. It is my understanding that no girls were arrested; just the house bosses.
While I am under the belief that in recent times these establishments booked mostly (if not solely) independents, I am also under the belief that they at one time indeed booked "trafficked" girls, for which were the primary charges.
The bust went down in many cities across the U.S. on the morning of May 24, 2016. This is a continuation of Federal case that's been developing since last year, which initially included numerous arrests made in other cities.
Google: thai sex trafficking
and read the many stories posted the last week of May.
Any ads for these establishments that are new are certainly on "auto renew" so do not contact them, as you may be texting a Federal agent... and if the numbers used by these house bosses contact you, be assured likewise, however I my belief is they are not after patrons, just the organizers and participants in the network.
Another site I frequent deleted the profiles of those houses, and thus the ads, though it was after much discussion and it was obvious that the ads on that site, which were generally updated multiple times a day, all of a sudden ceased to be updated.
While there were many lovely, good spirited girls at these places trying to earn a living for a better life for themselves and often those in their home country, some were not necessarily working under ideal conditions and got more than they bargained for when they came to this country. It is unfortunate that there are some true victims as a result.
Having had the privilege to have been rather well acquainted with a few of these amazing girls, I have reliable information about what I speak.
Be safe.
