I knew Masta as well and he was quite the boastful type as were a few others on IRC. It was only a matter of time before he was found out.
As for his customers they most likely can be charged and/or sued, but most likely the companies will settle with them at a cost. Now what if some of these people were paying for service but used an additional box, per the website, for "educational use"...would they still be held liable? i guess we can wait and see.
