The disinformation doesn’t really matter. The fandom wiki’s naturally become incorrect over time, since they’re typically no longer maintained after a community switches, so vandalizing it after the fact won’t really change anything. For Path of Exile, it took the developers linking to the new wiki, and about two years of the community sending new players to the correct wiki, before it even started to show up in searches. Even then, I believe the fandom wiki still shows up first if you look at some of the very old entries.
I get all my news from Lyle Rath on Pregame Discharge. He’s told me it’s the only videogame show, so I’m surprised to hear about all these other shows.
