Why am I not seeing the correct comments and vote tallies for certain communities from other instances?

I hope it's alright to ask a question here, because I'm very curious about an important facet of this instance:

I noticed this morning that when I visit some of the communities hosted on other instances, I'm seeing an incorrect vote count, and few to no comments. Is this due to the recent breach, and does it relate to defederating from other instances temporarily?
