That's the megaphone effect of social media. It LOOKS like thousands of people are supporting them when in reality it's a bare handful.
Not just that, there are dedicated troll farms for it.
Though not a game specific example, a relevant anecdote is that when Rush Limbaugh was being subjected to a cancel campaign where thousands of messages a day were flooding his sponsors and stations, he paid to investigate the sources and discovered that the ENTIRE cancel campaign was just TEN people using bogus internet accounts to appear like thousands upon thousands of outraged listeners.
If you don't think tiny numbers of the perpetually outraged aren't doing the same thing in the field of RPGs (and entertainment in general) then you're delusional. They are the fringe of the fringe and see nothing wrong with using lies and distortions so long as "justice" is achieved. The biggest con they pull, amplified by the internet and a willing media, is to present themselves as the majority when they're probably 1% or less of a given population.
