That's why my website has nothing and I mean nothing on it that can be related to anything in this industry....no acronyms, no reviews, no trail to online boards...I use a completely different online identity.

Any email from anyone that mentions anything remotely related to anything that could be used is deleted.

While nothing on a website or on a review board may be a slam dunk for the prosecution, it certainly helps with probable cause (or so I have been told).

If you get a chance to do so, you should read the arrest reports that are used to file charges in the misdemeanor arraignment courts in your area. LE has to articulate what led them to arrest the defendant. If the arrest was for driving under the influence the source of activity might be simply that the officer was driving down the street and observed the defendant's vehicle weaving.

In regards to advertisements on the Internet, the officer could state that he was perusing the Internet looking for advertisements for escorts, also known as prostitutes, when he observed the concerned website. He could ad that the Internet is widely used by prostitutes to advertise for business. That would be more than sufficient probably cause.  

There is a service in Southern California that captures the arrests reports that are used to file complaints and distributes copies of the reports to subscribers of the service.  Most of the customers are law firms.  I worked for a criminal defense law firm that used the service.  I read every report that was filed in both the felony and misdemeanor arraignment courts in Ventura County and the Western San Fernando Valley Branch of the Los Angeles Superior Court on the days I was in the office. I wouldn't even attempt to guess how many prostitution arrest reports I read. In the beginning almost every arrest was of a street walker except for the ones that were generated by complaints.  Unless someone complained, LE would only arrest street walkers and occasionally raid a massage parlor.

With the advent of the Internet and sites like Craig's List, street walkers started to disappear.  The very first stings were conducted in Hollywood wherein a female LE would loiter on the sidewalk and lure men to a motel room where he would be arrested by other LE.  Before long LE was using sites like Craig's List to lure male customers to a motel room where they would be arrested.  I noticed that LE preferred to advertise as a prostitute and arrest men than call prostitutes and invite them to a motel.  They seemed to arrest a lot more men because the men didn't screen like many providers do.

One of the attorneys who worked in the office wrote a book on the subject.  It was the most comprehensive publication I have every read on prostitution and how to operate under the radar.  He titled to book, "Defending Prostitution Arrest Cases."  He only sold the books to other attorney's because it would be a violation of the law to advise non attorneys on how to break the law. He obtained most of the information by simply reading a lot of arrest reports.

But they can watch a car for some minor violation and than stop.

So if they think a website/review/ad implies something illegal - no they can not arrest on that but may be probable cause to set up a sting?

The new gal that just posted in Phoenix board for example. Her website is like many I have seen. Huge list of illegal services she offers - terms with their sexual definitions- perfect arrest bait for solicitation don't even have to set up a sting.

But if website/ad implies money for sex as most do.. that is all they need for a solicitation arrest at least for ad/website if can prove she did the ad/site.

As I said in my prior response, police need probable cause in order "to conduct certain types of searches or seizures".  Pulling over a car is a seizure.  Merely starting an investigation is not.  That is where your analogy fails.

         LE cannot  lawfully detain, search, or arrest someone solely  bc they are black. Nor could LE lawfully detain, search, or arrest someone solely  bc they identified themselves as an escort on an internet ad that did not violate state solicitation laws.

         But you asked whether “ it is legal for le to CONTACT the escort from her legally worded ad to try to arrange something that would be illegal?” It would be equally legal for LE to contact a black man who lived in a drug infested community just to see if he would agree to participate in a drug sting.

           Now if we took the facts a little further and changed the question to “ it is legal for le to detain, search or arrest the escort from her legally worded ad to try to arrange something that would be illegal, the answer would be it is illegal  bc they would need probable cause to do so (let’s leave aside the scary question of whether the ad plus reviews and TER profile would meet the probable cause standard).

        So the profiling analogy you are thinking about goes to situations where LE interferes with the freedom of the person. Mere contacting on the basis of race or gender would not violate any constitutional provision that I can see.
