To be honest you've already shown how one man could potentially take them down:

    BFL would undoubtedly get bukaki'ed by government agencies if an investigation was to occur. Assets frozen etc
    BFL would get spit roasted if the FCC found they were selling these uncertified products, even if it is just $7000 worth in 9 months LOL


Why dont you just report them to said agencies, watch the run on the bank as it comes out that everyone's money thats tied up has been frozen and under investigation, there would be charge backs on cards done on mass.
