Cheebs spams my notifications by constantly tagging me in random photos. He'll raid a George Lucas photobook and tag me in every one, for instance. Or he'll randomly friend some of my friends, then post ridiculous stuff on their walls.
The problem with having Shake there is that Cheebs tries to impress him by doing the stupid stuff listed above. Plus he'll post dumb shit on my wall. I refuse to add any family members on facebook, but I do have a host of real life friends who I'd rather not have bombarded with ugly notifications from me.
