In the beginning, pop culture wiki TV Tropes licensed its content with the Creative Commons Attribution-Share Alike license for free content.
I suppose the morale of the story is, if you contributed to TV Tropes before summer 2012, you should know they're distributing your content under a license that you didn't give them permission to use.
Uhh..isn't that illegal?
Well, technically, yes. However, if no one cares enough (or has enough resources) to go up against a website whose content is probably not all that useful in a quixotic effort to gain some sort of satisfaction, the point, according to the law, is moot. If no one with standing cares and brings suit, then, to the court, no one cares - no harm, no foul. Thus it has been; so shall it be. Yay, American law!
