i'm trying to block someone on aim, yet they know i'm online. i tried blocking everyone that i would talk to who would also be on this guy's buddy list (it's a small group that can be easily contained), but he still knows i'm online. how is he doing this? are there programs that allow you to see people that are blocking you? i don't think he just has another aim name that i don't know about and is seeing me from that, i even set it only allow users on my buddy list to contact or view me and took them off.
