Depends. FTC suspects you of taking payola. They subpoena your blog's host to get your name and address. Your host refuses to comply because they are not in the US. The case fails due to lack of evidence.
I worry about the unintended consequences of this new law. Say I am paid to write a piece of (free) software by my employer. I use my blog to say how wonderful this is, without ever mentioning that I was paid to think it's wonderful. (Perhaps I don't even know that the money influenced my decision.) Should I be fined for this? Is the community better off without my writing? (Which is completely free and not even ad-supported?)
Anyway, I am all in favor of consumer protection... but I think the bad guys will get around this law, and "good guys" will be caught in the net. Restricting speech is a very, very slippery slope. (I am not even sure how comfortable I am with libel being illegal -- and that is a law that has been around for hundreds of years.)
Let's install video cameras in everyone's house so that the police can have video evidence of all murders and child abuse. Won't someone please think of the children?
