I dont quite understand the individual roles of DOJ vs SEC, but I do see that DOJ has been active in pump and dump prosecutions: https://www.justice.gov/usao-sdny/pr/manhattan-us-attorney-announces-charges-and-arrest-pump-and-dump-stock-fraud-scheme I think the MMs are also involved, as I remember several trades that were well below my buy orders, or above my sell orders. I think the whole way the shell was set up is damning, with similar sounding companies, sweetheart deals, shared management, etc. "Nor do I, that's why it was sent the do]j."
