Quote: DON'T ADD LISTEN UP!!!!!!! If someone by the name of j_neutron07 wants to add you to their list don't accept it. It's a virrus. Tell everyone on your list because if somebody on your list is adds them you will get it too. It a hard driver killer and a horrible virus. Please pass this on to everyone on your list. We need to find out who using these accounts. Sorry for the inconvenience. Right click on your group name of your buddy list and click Send Message to all.
Just to be on the safe side I recommend everyone scans your PC for viruses. Something seems to be going around.
