Didn't Flash games sometimes employ DRM-type stuff to prevent swf jacking? Check the domain, and if it isn't an approved on, fail to run / do something devilish

Didn't Flash games sometimes employ DRM-type stuff to prevent swf jacking? Check the domain, and if it isn't an approved on, fail to run / do something devilish like make the game unwinnable with a note about it being stolen. EDIT: Oh, you were saying Flashpoint got around some initial domain check. Perhaps the developer added multiple, one obvious, loud one upfront and a few more later in the game.
