At first probably just the nsfw instances since I’m not here for porn and foreign language instances since I can’t really interact with them anyway. That alone should help clean up my feed a lot. After that no idea, I’m normally fine just blocking individual communities but if I see an instance where I’m seemingly blocking all their communities, I’ll just block the instance.
I’m honestly not sure. I only just heard that instance blocking was coming with this update. I’m not sure if it’s like defederating (aka complete block) or just blocks their communities or what.
