The OTCBB/QB companies that did PIPEs with registered shares aren't part of the SEC litigation, but some of them have been hit with selling after the news about the litigation regarding illegal selling of OTC-Link (PK) stocks hit. I've started a separate chart in the iBox for those companies but the main focus here will be on the PK stocks where unregistered non-exempt shares were sold onto the public.
The Fairhills/E-Lionheart PIPEs were toxic dilution, but apparently not illegal if the shares were registered before being re-sold to the public.
