Vampy...
I have morcaan stalkers in my msn online... I know how to block them... and I had one stalker in my AIM online once... After converstion, I realized something not okay with him so I block him straight way... No bother ever since.
Funniest, I never forget in my life is Mayoische came to my msn online to fight morcaan stalkers and kick them out....
They haven't visit to my online ever since...
I was panic when I saw one of morcaan (sp) show his penis on webcam... on the same time as RR msn me... I asked him for the help how to block him... After that I learn how to block AIM or MSN....
But screen name of msn and AIM online stay unchanged because I know I can block them and remove my msn and AIM in my profile.
