Apart from usual ubo, reader mode and friends trained eyes are very effective content filter. We all can glance on a search result page or an article and immediately know if it’s content or low effort craps.
Stay out of mainstream social media, stop consuming ‘feeds’. Stay in the realms of personal sites, blogs and sane link aggregators/rss to keep mental peace of not having to filter garbage with eyes everyday.
Google without logging in with ublock is best. No privacy implication, no ads, no ai response.
