Wenchy, your PO box likely isn't good enough for a business license or occupation permit. We are all in business. That some of us choose to work from home doesn't mean that the rules of doing business should be re-written for us.
I am not for publishing model infomation online.
I am not against publishing of company information.
If the model information and the company information happen to be the same, well, then it is likely something that the model needs to work out for herself or himself.
I feel sad about the concept that some people may be driven out of the business because they are not able to publish their business address because of choices made in the past.
Remember too: Models that run their own sites are particularly in the deep end anyway, because they are the primary producers. I might be willing to accept the concept of a secondary producer being able to use a PO box or similar, but primary producers have major obligations under the law (even the original law as passed by congress) that cannot be sidestepped.
Her existing 2257 statement is invalid on it's face:

Sending the feds to a PO box isn't going to work. Regardless of old laws new laws she was not compliant. The records obviously were not inside that PO box.
The rest is the rest. If there is enough money in the business, rent an office and work from there 20 hours per week. If privacy is that valuable, then take the steps.
