I did that on a Yahoo swingers group. Had been going back and forth with a guy and he told me he was going to kill me. My first interwebs death threat. I sent him an email with my address, told him to drop by anytime. But to keep in mind I take death threats seriously, so his "killing" me wasn't going to be a fistfight. That since he had threatened me in a public forum, I was going to defend myself and my home and that chances were he would be catching a bullet. And that living where I live, where a castle is just that, no jury would ever convict me. He didn't want to play anymore.
