On version 0.19 you can block instances so that you don’t see any posts from that instance, instead of having to block communities one by one, you still see comments from users of that instance in other posts so it isn’t completely blocking the instance.
I 90 percent of the time browse my list of communities.
The other ten percent, I explore the All feed. It’s filled with so many communities that do not interest me.
I don’t think I will be blocking any instances for now as it helps in exploring new groups.
Same boat as you - most of my time is spent on subscribed, not /all
No need for me to block anything at the moment tbh…
