Just add aus99 to your search string:
Google Jessie aus99
Google Shop_name Jessie aus99
Google {nationality of interest} aus99
Google shop's name, then, in the results, look to see if that shop has a website. Visit the website to see if there are photos (even if dubious), rosters, map directions, WeChat, etc.
e.g. Google Summerville
Some shops use locanto for shop rosters. So include that in a string (add Sydney to avoid other cities' locanto listings):
Google shop_name locanto Sydney
Google maps, center on suburb, then search for brothels or massage parlors. In the list that appears, check out the shops' websites. Then use above to find info in aus99.
Google street view: useful to know what you're looking for, saves that embarrassing binary search...
Use the "Advanced Search", the link, VERY top right, below the search field box.
In the new window, in Keywords field: Maroubra
Additional Options: Find Posts: 6 months And Newer
That'll cut down the shop ad clutter.
=======================
Or try:
On the webpage: Forum: Sydney - After Report
Below the Thread Display Options section, below the Show Threads, on the right hand side, SMALL link to "Search Forum". In the pop up, type Mascot with the Show Threads radio button selected (the buttons below the field).
That will also cut down on the shop ad clutter.
Once you find some specific shop names, then search on those names. Sequential process, but believe me, worth the time.
