Yup, I get them every day. Are they the ones that popup with a box, and all you can do is click "OK?" If you're getting those ones, go to start -> run -> type "cmd" or "command" -> type "net stop messenger"
If it is AIM messages... well, you're SOL. The only thing you can do is block people not on your buddy list from seeing you. Or just start blocking the spammers one by one, but all they have to do is create a new name.
msg me or email me if you need anymore help.
