This post is for both ladies and gentlemen.
It should come as no surprise that there are prostitutes and escorts on Ashley Madison. If you've ever seen the news stories where people get busted in prostitution stings, it's usually from Backpage or Craigslist. Typically the people caught in the sting are more or less the usual suspects of various lowlifes. Notice that doctors or lawyers never get caught? It's because they're finding their fix through Ashley Madison. The smarter women of ill repute have moved their business to a more secure platform.
Ladies: Assume that some of your messages on AM are from someone on a vice squad. Sometimes they'll come right out and ask about prices for certain services or suggest to meet at a hotel. Both of these should be immediate red flags. For your first meeting or two, never agree to meet at a hotel, even if it's just in the lobby. Another tip for first meetings is to never, ever accept money--that's how you get arrested. Also take the additional step and mention up front that you're not an escort or hooker. If anybody presses you to take roses or donations (aka money) tell them no. My best advice for staying safe on Ashley Madison comes down to trusting your gut. If you think something is weird or wrong, it probably is.
Gentlemen: Much of the same advice applies to you as well. Stay away from hotels for the first few minutes, nor offer any cash. Want to pay for a lady's cab fare? Give it to the cab driver and not her. If you're planning a one night stand, take her to dinner beforehand so it's a date. Don't be afraid to ask if she is an escort. Just tell her you want to cover your ass.
Don't be afraid to ask questions. Don't be afraid to trust your gut. Stay the hell away from hotels. Be smart and you'll be fine.
