body: While poorly worded, another [question](https://law.stackexchange.com/questions/17218/linux-questions-when-moderator-do-not-care-about-keeping-the-laws-of-a-forum), which is currently on hold, brings up a good point: does a company have a contractual obligation to uphold its TOS, or can its moderators arbitrarily enforce its internal rules.
  
  
  As an example, can Facebook choose whether or not to enforce its TOS for some posts, and yet ignore their standards for others? It seems like the TOS is a contract, and it would specifically need to say in the contract that enforcement is at the company's discretion. Does Facebook have such a clause?
