Some of the Brokerages, notably TDA, are chilling buy orders on some stocks, possibly or likely because of their own Suspicious Activity Reports (SARs) and their Risk Management Controls.
There appears to be a disconnect between the Brokerages chilling buy orders but apparently not relaying the info to the SEC, Finra, the OTC, and particularly the DTCC. Maybe they are....danged if anyone knows.
There was supposed to be a repository database for ALL gatekeepers to input SARs and to access all the other gatekeepers' SARs.
After two or more SARs on a stock the SEC said they would get involved. Maybe they have, but the SEC is missing more scams than they're stopping.
