All you have to do is post 1 comment that doesnt perfectly align with their viewpoint. Then you get a downvote, you're now negative and your post becomes automatically hidden! Strangely enough, within minutes you'll be barraged by downvotes and witty unescapable reframes of your comment until you are about -100 and then it will stop. I would say they weaponized that sub, but I dont want to get Epsteined. At least in 4chan the worst they will do is call you names.
Love upvoting it here and there
