You should still pay for the content you consume. This is why these streaming sites get shut down so quickly. Watching a stream is no different than torrenting it or other means of infringing. You're watching a TV show without the rights holders getting any money. If you don't want the rights holders to get any of your money (whether it's because you cannot afford to pay, or do not want to pay), you simply should not watch the show, not find a free way around the system.
