I'm still trying to figure out how slander on twit

I'm still trying to figure out how slander on twitter and FB can be prosecuted, but slander on Ihub cannot. It's especially frustrating that the admins are obviously complicit. Yes, I understand that the SEC turns a blind eye to OTC manipulation crimes, but this is actual FRAUD. Hollywood weirdos are currently being prosecuted for buying admission to colleges for their kids, why hasn't the FBI gotten involved in the blatant fraud happening on Ihub? This AM, an army of obviously paid trolls besieged the VYST board until the pps got knocked down....then they all disappeared. All of them were new faces. These things don't happen by accident. It was clearly organized and coordinated.
