I could be wrong, but I think one of the reasons the site doesn't actively label or promote the Singles Forum as a "dating site" is because of too many crazy things that happen when people are given the possibility for romance.
I've been here 15 years, have seen and heard a lot of things -- jealousies, stalking, having to get the police involved (in more than one instance, and to more than one person) because of someone who wouldn't accept "no."
Sometimes I think it's even more harrowing than on a secular site because some people will use the excuse, "But God told me you're the one!" And if someone is convinced GOD told them something, good luck changing their mind -- even if it's all just in their own head. All kinds of one-sided pursuits seem to happen that are annoying at best and downright dangerous for the object at worst.
People are going to develop attractions to others no matter what, but setting some parameters seems to have helped cut down on a lot of the riff raff, since those who aren't interested in taking the time to get to know people in the threads leave immediately.
I'm sure we lose out on a lot of good people that way, because it's not for everyone, but it also snuffs out a lot of people trying to find "instant" connections, and then the next one to move on to when they get bored.
