The original Dislike activity (https://endlesstalk.org/activities/dislike/e1f82f6a-d49b-4dab-b444-36c382f13c5a) has a record at endlesstalk.org, but the Like object’s activity that’s been undone doesn’t (https://endlesstalk.org/activities/like/1f0b6132-547e-4fb5-8313-6f7b7f31be6b just returns ‘No record found’)

I got the same results when I tried this from lemmy.world (but I thought I’d try again from a 0.19 instance)

I found some references to this at the GitHub, but they were issues that were closed off as being fixed, so I don’t know what the situation is with this now.

    I would argue that I’m not asking it to be a queryable thing or a datastore. I wouldn’t expect a community’s ‘Accept’ of a ‘Follow’ to contain loads of data about past activity because that’s not a logical or practical thing to encapsulate. For an Undo though, there’s already a small, fixed-length encapsulated object inside, consistent with how ActivityPub is used for other circumstances. Since it’s there anyway, I don’t see the value in it containing incorrect, made-up data, when it may as well have the correct data.
