There's probably more than you think -- they can just hard to find due to the shortcomings/user hostility of Google, as has been discussed here recently [0].
As a concrete example, searching for "Rabi-Ribi wiki" for info regarding a somewhat obscure 2016 Japanese platformer bubbles up the usual Fandom spam garbage to the very top, followed by a copycat site "PCGamingWiki", followed by more generic information such as its Wikipedia page. It's only if you get to the second half of the second page results that you'll find a link to RabiDB [1], which is extremely comprehensive, ad-free and documents pretty much every detail about the game.
In a similar vein regarding the original comment, there are a lot of forums with very active user bases that will never show up at the top of Google results. I still post in one regularly with ~300 daily active users who have all known each other for years, for the most part. We'd never show up anywhere near the first page of a Google search result, though, so we essentially don't exist on the modern internet. I imagine countless other forums are in the same boat.
What do you mean by PCGamingWiki being a "copycat site"? Copying who? It's always the go-to site I use to check various technical details on games and any tricks that can be done to improve shortcomings of especially older games.
