As a user of the website for many years it's entirely obvious that a majority of the website is gamed (besides its niche corners). Reddit's bot prevention mechanisms just fuck VPN users - they are wholly inadequate.
That thread is evidence of a organized bot campaign that they had 12 days to clean up (and didn't). It's naive to believe that the rest of the website isn't similarly (and less obviously) affected by bots - with vote manipulation still standing.
