Most John´s get in trouble when vice sets up a sting and it is usually either in a hotel room or on the street depending if they are setting up a sting for hotel or street prostitution. Not for what is written on a website or a computer or phone.
To vice it is a production line where they would want to "produce" as many successful arrest as possible on that day they have the sting. They have multiple task to perform so they do not set up prostitution stings every week more like twice a month a street prostitution bust and the twice a month in a hotel. The other days of the month they do check on liquor licenses, game license etc etc.
At these few times they set up the prostitution stings they have to have the John´s specifically say "what" they want for "the money". If a John say massage then he will get a ticket for hiring a unlicenced masseuse. If the John does not say anything and do not hand the money and leaves, there will be no consequences.
Same goes for the stings where the escorts gets set up in a sting. You do not want to take the money because then you get a ticket for escorting without a license unless you say you are giving out sex for money then you get arrested. So best for both Johns and escort is to say nothing and not pay or give money and just walk away.
I have ONLY in very few nationwide large sting operations seen more detective work being performed like going through phones/ computers. Then when it comes to court it get´s dropped because what you say in writing some where does not seem to stick unless you admit to anything in court. The people who does not say or admit to anything walks without charges.
Saying you get in trouble what you wrote on a website somewhere will get you in trouble is not true. I would say that would be your rights to freedom of speech. Think about it, if you wrote a fiction book or an article on "how to" kill someone, you would not necessarily get arrested for that unless you specifically threatened someone. Same thing here, by you writing about paying for sex does not mean you can get arrested for writing about it. They have to set up a sting where you admit to wanting to pay for sex.
I mean let´s say I retire and I get arrested a year from now because of events that happened a year or more ago. That would not happen for these type of crimes. Same goes for you who writes about your experiences in reviews.
So, do not be afraid of what you write and try to hide in panic. With a better understanding you can be more relaxed and hobby without so much paranoid fear.
Makes sense
