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.
For now, I blocked three communities, one about gossiping and two about adult material. I also blocked a bot that keeps cross posting things from Reddit. That’s all that I blocked so far.
