uBlacklist is a great tool to block sites you don't want from showing up on your search results on google (and a couple others including bing and duckduckgo). It supports regular expressions as well, I use /pinterest\..*/ to block all pinterest-related content. https://addons.mozilla.org/en-US/firefox/addon/ublacklist/ https://chrome.google.com/webstore/detail/ublacklist/pncfbmi...
I wish Google would add that feature natively. Google could even use it to help detect spam sites.
Oh wait, you don't have to imagine, just use Gmail on Android. "Spam? That's not spam" - Google.
Or just Android with it's fucking "notifications" from all the garbage news sites. Tbf, my fault for using Google apps.
Honestly, blocking shit you don't want to see locally is the best solution. Decentralized, under your control, no need to trust BigCorp number 294.
