Going cold turkey on Twitter (and Facebook and the like) was amazing, but the problem for a while was that you'd still end up browsing it by proxy because it would all get screenshotted for Reddit.
It's been a long time since I've seen them (thank god), but the worst culprits were subs like facepalm, white people twitter, leopards ate my face, and pretty much any left-leaning or liberal sub.
They did a fantastic job of platforming the ideologies they stand against simply by screenshotting the most vocal advocates and talking heads and sharing them so commenters could get angry. That shit lived rent free in the subscribers' heads to an unhealthy degree and for everybody who hate-engaged, there were plenty more who saw it as an introduction.
One day I'll do for Reddit what I did for the rest of social media but for now it's easy enough to stay off Popular and All and just stick with the smaller subs with a specific subject matter.
