So my friend played a prank on craigslist. He pretended to be a girl and answered those mm4w ads. Those ads usually have a title and a age. On those ads its usually something like "title - age - location" The thing is that hes afraid that he might have answered to something like this "two hot guys looking for hot chick - 1717- usa". Back then he doesn't know what the "1717" meant. He thought it was "one thousand seven hundred and seventeen" Hes now afraid that he might have accidentally answered one of those ads and is afraid that it might be an undercover police officer or something. Should he be worried?
