I found that things became much more pleasant on here when I blocked hexbear. I recently blocked lemmy.ml as well, but I may reverse that if I find that I’m missing too much good content.
I’m open to other ideas on how to mostly avoid people who love conflict or argue in bad faith.
I usually only block communities, like NoStupidQuestions. There are actually quite a few stupid questions that can be asked, it turns out.
The only other instances I’ve blocked are HilariousChaos for all the spammy/unfunny communities they make and most of the foreign language instances.
