This is a version of the fake dating sites. They have profiles of people but no one responds. It's a scam.
I reached out to several of the housekeepers listed and none returned a call. They did send me a couple of requests but they didn't call back either. It wasn't as if I put anything in my reply that would have turned anyone away. My response was always. "Need housekeeper one day a week." That's it.
Pros and Cons:
Bottom Line: No, I would not recommend this to a friend
