Back in ‘06 just after my divorce, Yahoo had a dating site (eventually bought by Match and ruined). The site had “romance” chat rooms that were an absolute hoot. They were divided by State and the larger States had multiple rooms. A bunch of us regulars would show up frequently and have meetups. It was wild. Anyway, there was a function where you could request to have a private chat with people. About once a month I’d get a request and shortly into the conversation they’d reveal that they were really 16 or 17 years old. Immediate block obviously but I suspect most of them were narcs or Perverted Justice types rather than actual teens.
