Comment on The two most upvoted comments on any Lemmy instance are on Feddit.dk, but you won't see them on your own instance

  This is in fact how Feddit.dk knows that the Like came from mastodon.social at first. The problem is that the signature is a HTTP Signature which is only associated with the HTTP request that mastodon.social makes to Feddit.dk. It is not on the Like object itself. Thus that signature can’t be transferred to the Like object if Feddit.dk wanted to share it further.

      Yes, fetching the URL directly would be a way to verify it. I don’t know if Lemmy currently does that. In any case, it seems very round-about.

    So there’s no way for feddit.dk to translate into a Lemmy style upvote?

      There’s not such a thing as a “Lemmy style” upvote. It’s all Like objects under the hood shared via the ActivityPub protocol. But ActivityPub has no mechanism for sharing an activity further than the original receiver (i.e. forwarding from A to B to C and so on). It’s really only made for direct sharing from A to B.

        Ohh so the object doesn’t change at all through the process. I see the difficulties

    So we need to convince the mastodon devs to change it so the signature is on the like object itself.

      Unfortunately it is not that easy. It’s not Mastodon that places the signature like that, it is the ActivityPub protocol. Lemmy, Mastodon and all other ActivityPub instances do it this way. You’d need to extend or change the protocol to somehow fix this. That is not easy and not something that will be done overnight.

        Of fucking course they did it that way. If i where to hack sonthing together u could also just quote the entire request signature and all and forward it.
