You read the documents, did you not? Unless you just decided to sign them without reading it all in which that is your own undoing. And let me quote:

"I, blankity blank, do hereby consent to participate in the Game, and accept all burdens and responsibilities which are carried with participation in the Game. I hereby concede to all conditions that may be inherent in accepting to participate in the Game, as they may pertain to the Game, both stated and unstated in this legal document."

[Kami help her, does no one read agreements anymore?]

In other words: you agreed.
