Now that makes sense, digaran.  Neither the manager nor the campaign participants had any knowledge of wrongdoing on sinbad's part--and how could they?  All of these charges were just recently made public.  Mixers aren't illegal in the US as far as I know, so everyone involved in the campaign was acting in good faith by assuming sinbad wasn't guilty of something....kind of how we should treat any project that doesn't show obvious signs of shady shit going on.

The justice department goes after big fish, not minnows.  If they took any action against campaign participants, I'd be very surprised.
