This was about Elon's "Nazi salute" and both so incorrect and blatantly astroturfed I haven't returned to Reddit out of disgust.
A ton of near-dead subreddits with no activity and no reason to link to x.com for any reason suddenly had thousands of people show up demanding links to x.com be blocked like it's an everyday problem for the sub.
The quiet beneficiary of this campaign are those who benefit from Reddit's groomed narrative and their competing platform Bluesky.
