warning about the "Your Friends-Only Post Has Been Stolen" IM thing going around. I'm just repeating it; I got one of these last night from an AIM username that was racist in nature, so I explored the provided link with wget, and it's just full of all kinds of nasty.
Do not click on the URL if someone sends you that message in IM. I didn't do any sort of an in-depth analysis other than looking over what you get back in the initial wget response, but that was enough.
