How do you trace IM addresses?

Question

I got a threatening IM from someone on Yahoo Messenger, not sure whether it's a joke or my ex but it's scary. No one has my ID except for my ex and people on answers and I wanna know whether or not to be worried about it. Thank you for any advice!

Answer 1

First off if your ID is visible on yahoo answers then anyone who has access to a computer can get it.

For now I'd just take it as a meaningless threat unless it becomes repetitive.  You can always open a new email account and get a new ID that you can keep PRIVATE
