Not a lawyer, but pump and dump schemes are illegal under existing law: https://www.investopedia.com/terms/p/pumpanddump.asp Even if the motivation of the 'pump' aspect is perceived to be righting a wrong, consumers left holding the bag will be harmed. The companies involved are intervening to avoid additional liability (they may already be sanctioned for not having safeguards in place). There will most certainly be civil and criminal investigation into the users involved. Although I doubt the government is equipped to investigate the sheer volume of material.
