I just want to say is that it's not only fandom that has its dangers. A friend and I fought, didn't talk any more, until I started a livejournal, started using Y!M and AIM, when I moved away, in order to keep up with those I wanted to keep up with. It was really scary when this ex-friend began to contact me again. However, we now have a court-order saying he's not to contact me or be anywhere near me (I think it's 1000 feet), so that has me feeling somewhat better.

I've only had one bad fandom experience, as far as being uncomfrotable with a person I was in contact with, but I always made sure it was easy to break ties (block emails, IMs, etc). I hardly use my real name any more, never give my phone number or address (I've been thinking about my PO Box, though, with christmas card season upcoming). It's really kind of upsetting to me when I see my friends giving out their info willy-nilly, but that's not my choice.
