Yes, you can block communities. Instances are a little more complicated since that’s defederation and happens at the instance level, but since you won’t see posts from communities you aren’t subbed to that’s less of an issue.
I have seen posts from instances with communities I’m not subbed to on the kbin “All” list because someone else on the same kbin server subbed to it. It makes discovering new communities very easy since I don’t need to do all the leg work on my own.
