Well, I don't think anybody should post their e-mail address in an open forum. It exposes people to Spam and other nastiness. We try to allow people to have anonymity if they want it. It's too bad that a number of people have chose to abuse that anonymity.
How should we treat guests? Well, it they are civil, treat them civilly. If they are assholes, act as if they don't exist. As always, the best way to combat flamers is to act as if they were invisible.
