Yes, sting operations are legal. Police can pose as clients, post decoy ads, and arrest people who respond. Entrapment is a defense, but it is a narrow one: it requires showing that law enforcement induced the defendant to commit a crime they were not otherwise predisposed to commit. Simply providing the opportunity to commit a crime (a decoy ad, an undercover officer waiting at a hotel) is not entrapment. The defense gets traction when officers push past initial refusals, escalate the sexual content of the conversation themselves, or repeatedly re-contact a target who has walked away. We subpoena the complete text thread and audio to find those moments - and police reports often cherry-pick excerpts that make the defendant look more predisposed than the full record shows.
