So are we theorizing it's an ex-member who was banned based on black or Jewish issues?

I wouldn't narrow it that much. My guess would be a former freeper who was banned for any reason, and gets his jollies posting the most repulsive stuff he can think of, as his "revenge."

So is the targeting just a ruse?
