I am sorry, but not sure how the FCC has any jurisdiction here. However, I can see the issue with them being small and hard to and track, but still not sure how FCC is even the right entity to handle this.
However, the US is also is weird for instance taxes are based of citizenship not were you live geographically. For instance if you have lived in Japan for 10 years you still would have to pay taxed back to the US.
