IMHO - "Support" hardly counts when it doesn't cost anything, and when it doesn't do anything other than make the "supporter" feel like he's doing good.
And honestly - how does seeing a cartoon avatar make the unaware person aware of child abuse? If he heard about the sheeple thing, he was already aware, and if he hadn't heard about it how can he know why everybody has Scooby Do up instead of their own pictures?
