You generally have to trust the people you're dealing with
Not so much on an anonymous forum since actual identities are hidden, and people tend to think they can safely say anything. The only one here who is really putting his trust in us is JMT, giving his real name and Facebook ID.
What we're really doing is trusting that no-one cares enough to try tracking us down in person, to put reality to the stories. Or a bullet to our head, depending on the degree of sanity held by people who argue with other people on the internet.
I am as sure as anyone that our regular posters are harmless, but we have lurkers and this is a public forum. That, for me, is a consideration in how much intimacy I would be willing to share.
