In my personal opinion, this site is completely unusable without heavy content filtering. Just being picky about which communities to follow and users to block isn’t enough.
That said, I realize I might be in the minority on this, so I’m curious what others are doing to preserve their sanity.
I browse /all and block communities I’m not interested in.
I only block users who are spamming, trolling, or harassing. I don’t really like blocking people. Everyone has a bad day sometimes and it shouldn’t count against you in the long run. Of course, if you just come here to exploit people, I don’t think you have anything to offer so I will block someone like that. I’m not here to spend money, so anyone who exists to extract money won’t have anything to offer me.
