I was poking around my AIM and discovered that I can see who has added me to their buddy list, unless they have it hidden.
Turns out I'm on 91 buddy lists, including those which are hidden, but I have only small amount in my own list.
Some of the buddylists that are visible seem to be bots, because their personal messages are exactly the same. Then there's a few who have never talked to me.
It's rather funny, in a way. People get my AIM and add me but never talk. I've had those who randomly IM me asking who I am and how they don't remember where they got my AIM name.
I use AIM as my public messaging program where people can contact me, so I don't mind at all when people add me. It's just funny when some people add and then forget.
