Pretty much nothing. Take this quote for instance, while it's not DIRECTLY talking about what's allowed, it hits it in the ballpark:
_**"Now let's take up the minorities in our civilization, shall we? Bigger the population,
the more minorities. Don't step on the toes of the dog?lovers, the cat?lovers, doctors,
lawyers, merchants, chiefs, Mormons, Baptists, Unitarians, second?generation
Chinese, Swedes, Italians, Germans, Texans, Brooklynites, Irishmen, people from
Oregon or Mexico. The people in this book, this play, this TV serial are not meant to
represent any actual painters, cartographers, mechanics anywhere. The bigger your
market, Montag, the less you handle controversy, remember that! All the minor minor
minorities with their navels to be kept clean. Authors, full of evil thoughts, lock up
your typewriters. They did. Magazines became a nice blend of vanilla tapioca. Books,
so the damned snobbish critics said, were dishwater. No wonder books stopped
selling, the critics said. But the public, knowing what it wanted, spinning happily, let
the comic?books survive. And the three?dimensional sex?magazines, of course.
There you have it, Montag. It didn't come from the Government down. There was no
dictum, no declaration, no censorship, to start with, no! Technology, mass
exploitation, and minority pressure carried the trick, thank God. Today, thanks to
them, you can stay happy all the time, you are allowed to read comics, the good old
confessions, or trade?journals." **

This is from Beatty in the book Fahrenheit 451 and it means that nobody wants their minority-toes stepped on. Everyone wants to be happy and God forbid somebody's feelings should get hurt, so destroy everything that might possibly, in any way, offend anybody. In this book, its books. So in our world, its anything that hints at offense-ment. And THAT can be applied to league.
Does that answer your question?
