a number of subreddits like r/ConsumeProduct were taken over by the hate mongers from the_donald. You would have post brigaded to the front page that had absolutely nothing to do with consumerism or product promotion
I should be the prime target for a community sarcastically titled “consume product” as I hate spending money wastefully and enjoy getting good mileage out of anything I buy. Instead I learned how to block subreddits on my Reddit app of choice because the content had absolutely nothing to do with criticizing wastefulness. I could never quite put my finger on what the subreddit was designed for (I never subscribed, I only interacted with it when it hit /r/all) but I knew it wasn’t a criticism of wasteful consumerism.
Social media has a trolling/brigading/hive mind problem in general across all platforms and I would add solving this problem to Paul Graham’s list of “frighteningly ambitious” ideas.
Can you link to an example? Oh right...it's all deleted, so we'll have to take your word...and your definition of whatever you consider "hate"...which has no definition...
