escort app/website called 6 or Six

a bartender told me about a website or phone app called "6" or "six" with lots of escort and massage ads for whatever city you're in. I tried to find the website/app but nothing comes up. Anyone know about this "6" or "six" app?

The only one I could find and it's overseas

Double post.

Don't know if this is the place, but West of Tampa - https://www.the6shops.com/

Slixa maybe??
