nekr0zWhile trying to nail down #2490 I noticed code in Idno/Common/Entity.php that looks like it's supposed to remove annotation when webmentioned about removal. However, I couldn't help but notice that when I delete my own testing replies to my own testing posts, the annotations on post stay.
[mapkyca]Known should definitely send webmention on delete, but I think the view was taken that Known wouldn't remove comments on receiving a delete webmention, on the grounds that a third party shouldn't be able to remove content from your site. That said, maybe logging a "remove request" would be smart, or more generally "change requests" with versioning, for edits and stuff.
