Regarding young (over 18 of course) CL girls with  who post multiple ads with pics and work out of hotels...some are well reviewed providers (more than 4 reviews by reviewers that have up to 20+ reviews) and have good reputations on other boards..I have no doubt they are legit, but must attract LE interest esp. in OC.  Any significant risk of a hobbyist getting busted seeing such a girl?  Let us say one gets arrested....anyone reaonsable chance a girl would be asked to set up clients?

Yes and yes. It has happened before. Caveat Emptor definitely applies here.

Operating out of a hotel is high risk for getting arrested.  Undercover detectives in fact look for these types of CL girls for entrapment.  Clients should be interviewed for positive negotiation for mutual consent.

what did yo mean by "client should be interviewed for positive negotiation for mutual consent"?
