I never really used social media because I had such massive social anxiety. But I did used Reddit (a short time) and YouTube

Reddit was easier because it had such montonic boring far-left content smeared everywhere. I just uninstalled the app and poof it was gone. I had urges to reuse it, but it was short lived

YouTube was much harder because of its very good recommendation algorithm. Even if I uninstalled it, I couldn't stop myself from reinstalling it after a while. If I managed to keep the mobile app at bay, there was the desktop web version waiting for me. After a lot of infighting with my addicted brain, I now have NewPipe with all the Trending, Subscribed, New Videos crap disabled. And on the desktop side, I redirect youtube.com to piped.video, another non-addicting YouTube frontend

I couldn't have been happier in my life before because of this small change
