Well you make your own decisions in life, you cant say if everybody say because you are responsible and if you cant evaluate the risk whit investing in a suspect company whit no address I think you deserve to get burned in orther for you to start think independent and hopeful you wont make the same mistake twice.
And the company perpetuating the scam deserves to have the worst imaginable punishments cast upon them. Public doxxing, swatting, filing of criminal and civil cases, reporting them to the SEC, using social media to defame their character and family, showing up at their doorstep and challenging them to a duel with pistols are all called for, given the appropriate context is present.
Of course I'd settle for simple prison terms, so long as they get put in one of those "Federal, pound-me-in-the-ass prisons." A justified penalty as well.
