How to see all the communities an instance has blocked from other instances?

It's easy enough to look at https://[instance]/instances and see which instances a particular instance has blocked.

But in the cases where an instance hasn't completely blocked another instance but has blocked specific communities on other instances...where can I see/find that?

So far, I've found that reading and parsing the modlog will reveal that if you are willing to search for it manually, but is that the only way?
