Faking it

There is no spoiler time frame. People are gonna do what they want on the internet regardless what you think they should do. If you don't want spoilers, it's your responsibility to ensure you don't see them, not everybody else's.

"its your responsibility to ensure that people arent complete fucking useless assholes to you, not the responsibility of said people to not be assholes"

Why are you such a dick ?

You aren't gonna stop people from being assholes, so your only workaround is to just stay away from the internet if you want to avoid spoilers. I know for some reason everybody likes pretending it's a perfect world where telling someone they shouldn't do something works, but it doesn't. Staying away from social media and websites like this is your safest bet to avoid spoilers. You don't have to like it, but that's just that.
