Alright, thanks for letting me know what it was. I'm absolutely positive that it wasn't me who griefed him. However, if my name appeared when you looked it up then I guess my brother did indeed hack my computer. Can I ask what kind of grief it was?
Also, since getting hacked would be my fault for not locking my computer I'll accept any punishment I get. I'm really sorry and will apologise to spamarian as well in a pm.
