> Penalties to be applied in cases of criminal copyright infringement (i.e., violations of 17 U.S.C. § 506(a)), are set forth at 18 U.S.C. § 2319. Congress has increased these penalties substantially in recent years, and has broadened the scope of behaviors to which they can apply. See this Manual at 1847.
> Statutory penalties are found at 18 U.S.C. § 2319. A defendant, convicted for the first time of violating 17 U.S.C. § 506(a) by the unauthorized reproduction or distribution, during any 180-day period, of at least 10 copies or phonorecords, or 1 or more copyrighted works, with a retail value of more than $2,500 can be imprisoned for up to 5 years and fined up to $250,000, or both. 18 U.S.C. §§ 2319(b), 3571(b)(3).
If you broaden it to include DMCA violations you could spend a lot of time in jail. It's even worse in some other countries.
