I'd propose the creation of a tax evasion wiki on Torland, so people could share tips and such. But it could backfire, as nothing would stop the thieves themselves to learn from such wiki how to catch more people, or write false tips ("baits") on it etc...
How hard it is to not file depends on where you work. If you work for a corp that made you fill out a W-4, forget about it - you've already contracted with the Fed by signing your name to a SSN.
If you contract yourself out for cash and bitcoins, you don't owe taxes anyway. And there is no way for the IRS to prove what you made.
