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.
Had a look at some of the commenters profiles, 1 littlerally said in their bio “proud scalper”. Many had posted in various sale groups at very convenient times and a couple I traced to various other sites.
