This is one of the main reasons I use Kagi. I have sites like fandom and fextralife blocked in my search results.
One of the things I miss about early internet years was all the independent fan sites and forums people had. Now, so much is just posted to these garbage platforms that control everything.
I’ll recommend a few from different genres:
Fextralife embeds their twitch stream into their site, artificially inflating their twitch viewer numbers, which in turn hurts smaller streamers since fextralife will be sorted first by viewer count.
