I like RubMaps.com better because they have more reviews and I travel frequently. NR in my opinion is more for escorts. Another good source of information is backpage and craigslist.
I always thought the police were in on it.
In San Diego, they even prevented a place from getting shut down.

I think in San Francisco, they leave the good places open and have to bust a few here and there just to keep the general public happy.
My 2 cents.
