If my account is on Blahaj and the community I moderate is on another instance like lemmy.world, and the user is from an instance we defederate from like hexbear, I won’t see the hexbear user’s comments (or even their user if I search for it) from my Blahaj instance, and so I don’t see a way I can moderate their comments on the lemmy.world instance I moderate.

Does this seem right? Is there any workaround?

(I guess I could make an account on the same instance as the community I moderate just for moderating that instance?)
