Uhmm... Okay, fun.
I've been threatened. A few times with death, but that was by idiots and twats, so y'know. It doesn't much count for shit.
I've been threatened to be hacked, but now I have a cop friend who checks over my pc a lot to make sure nothing bad gets in, and if a hacker does get in, he can trace it and get them into trouble.
I've had some teeny other threats, but I don't usually listen to threats. They're just silly anyway. I've threatened to beat the crap out of someone before, though, and low and behold, the week after that, I did.
