The Asian ads that were flooding the Portland area suddenly all gone??  All of them?  Did I miss something?

I've noticed that all the ads get pulled just before new providers post their ads. Sometimes its a couple hours, others a few days...

I wonder who/what is running that show.

before the ads disappeared they seemed to change the line-up every couple of weeks or so for each ad, but then they were all gone and are now starting to re-appear.

...spam-like Asian agency-posing as independent (using fake pics) ads.  
Upstate NY, Nebraska, Iowa etc too.

I was thinking of calling one of the new numbers for Asian providers in Portland, really servicing South Portland though.  So checked the blotter and lo and behold, a ton of arrests for prostitution.  I'm not saying it had to be those Asian ads, but with one good known one leaving and new ones there not yet reviewed, it seems suspicious to me.
