It's not technically, but movie and TV pilot screenplays circulate a lot before they get produced, because the creators want people to read them in order to fund/produce them. They're often rather different from the final shooting script.

On the other hand, scripts for TV episodes after the first generally have to be "leaked", which doesn't happen very often. But again, once it's out on the internet, the cat's out of the bag.

So production companies try to prevent scripts getting leaked, but don't really go after anyone once they're already out.

Plus acting studios use all of these in classrooms for training actors. So even if you did get the episodes "taken down" from websites, they're still circulating in classrooms in NYC and LA.

Of course, if you leak a non-pilot episode before the episode airs... let's just say don't ever expect to work in Hollywood ever again. ;)
