Virtually impossible? OMG, are you serious? Let me guess, you're a millennial.

Avoiding spoilers? Just don't click on the links. What's difficult about that? Don't you have self control? Stay off social media if you can't control your link clicking or are concerned about spoilers. Avoid certain websites that push spoilers. Do you have a life outside of the internet? Sounds like you have self control and social media addiction if you can't live a day without being online. I watch Survivor every week days after airing, while avoiding spoilers. I've seen a Super Bowl tape delayed 3 hours after the game was over, didn't know who won until I finished watching. It's not difficult if you aren't addicted to the internet and social fucking media.

The days flips at 12 midnight, so logically, streaming companies release at midnight as it's the start of the day. HBO releases some shows "live" at a certain time every week. See the difference? One is a live airing, one is posted online for people to watch when they want. Two different business models.
