I've spent a lot of this week blocking news communities and anything related to politics, ongoing conflicts, places that hate me because of where I live, and just anything that puts me in a mood.
It's been getting quite slow on my front page as a result.
If I want to be pissed off and anxious about things outside my control, I have another account on a different instance. I used to be a prolific commenter but since I made this account I've been using the other one less and less. It just gets me down.
Block things. You won't regret it.
