It's probably better to just stop using social media. (And stop tolerating people that do.)
I doubt that even something as 'light' on that spectrum as Hacker News is worthwhile enough compared to the non-social-media alternatives. (As a reminder, you can have a tree-like discussion structure without an upvote system.)
Have an ironic upvote. HN's system of not explicitly showing post scores and using accumulated score to give access to downvote buttons etc is the least bad that I have encountered.
