Yeah but AshleyMadison is just a hookup site.
And if you want to meet up for a one night stand you don't need to spend 200 hours online getting to know someone's soul. It's just photos, chat briefly, meet up, have sex, and then forget you ever knew each other.
It doesn't need high tech technology, especially considering how many guys could get blackmailed or scammed for having an adulterous video chat.
