A bit ago I posted on reddit about how gameboys (handheld console) were getting more expensive and Scalpers were making it worse. For a bit the post maintained in the double digits with the occasional scalper downvoting. I went to bed and the next morning- Boom. I had been spam downvoted by people who’s main activity is on Scalper subreddits and marketplaces.
Ha! Fat finger syndrome! Caught me before the edit.
I find it weird you called it “groupthought” when the word is “groupthink”, and you even linked to the groupthink article.
