[Terr_]

Strictly speaking, "piracy" means something involving international boundaries, planes/ships, and violence or coercion...

But seriously (and colloquially) "piracy" is still not specific enough if you're asking a legal question.

Do you mean only plain copyright infringement?

Unlicensed use of spectrum with "pirate radio"?

Secretly re-selling portions of you phone's data plan via tethering?

Bypassing electricity-meters and wiring your house up to the grid directly?

...Abusing a promotional offer that says "one massage per person"?
