There are no sexual services being bought or sold. It's like any other cocktail party.

There was a local bust recently of a membership provider discussion/advertising board.  News reports were that LE attended at least one M & G, a good way to ID the guys who ran the site and were later arrested.

If you attend one, why not just photocopy your driver's license and clip it to your shirt pocket?

...There was no raid, but information was gathered which resulted in some arrests at a later date.  Supposedly, LE got in to the M&G due to the sloppy screening by the host - a now-defunct agency.

Also, a reporter was allowed to attend a M&G in NY a few years ago without the attendees knowledge.  The shit hit the fan when he wrote an article about it.  The host of that M&G was appropriately disgraced.

... frequently by creating an account on a local website or even TER. They shmooze the chat rooms,troll the boards and sometimes even write a fake review of a fake provider and you get the idea.

Meet n Greets arranged through TER's MnG board tend to be organized by hobbyists and providers well known to their communities and fellow sex workers.

Closest thing to a raid at a Meet n Greet: A vindictive person drops a dime on Super Bowl Sunday and the cops show up to the back room of Tommy Rocker's where about 30 providers and hobbyists are sitting around with their clothes on watching the game.
