So, what would happen if there is no original message anymore in the feed and you encounter an “edit” subject?
We’d have to classify this as invalid and discard it. If the referenced twt is not present in the feed (or any archived feed), then it might potentially belong to some other feed, and feeds overwriting the contents of other feeds is pretty bad. 😅
As @prologic@twtxt.net said, clients must always check that twts referenced by edit and delete are actually present in that very feed.
@lyse@lyse.isobeef.org I think that’s what we would have to enforce – otherwise we’d run into the problem you’ve outlined. 😃
@lyse@lyse.isobeef.org @movq@www.uninformativ.de So a client that has the idea of a cache/archive wouldn’t necessarily have to re-check that the Twt being marked as “edited” belongs to that feed or not, the client would already know that for sure. At least this is how yarnd works and I’m sure jenny can make similar assertions too.
But yes, at the end of the day if the edit request is invalid or cannot be verified, it should be ignored as treated as “malicious”.
