Not totally true. Tim Sköld, Chris Vrenna, and Fred Sablan hardly ever post on Facebook. To be fair, though, the three of them had careers before Marilyn Manson, so the fact that they're all doing pretty well isn't too surprising.
Usually when people bitch about wanting ex-band members back, they talk about the early ones. I didn't even think about Fred & Co. Obviously he's a cool and talented guy, Chris Vrenna, etc. too.
