I've significantly reduced my time on Reddit. Used to pull up the website out of curiosity every day but the atmosphere is incredibly toxic. My front page was riddled with Russiagate stuff too for some reason and every time you'd bring up an argument that isn't the norm you get a mob after you.
Turns out if you unsubscribe from all of those types of subs, Reddit becomes a really funny and interesting time killer where the community actively tries to come up with ways to make you laugh.
