That was output from the profile button “Download my Posts” from two sites that I am a user on, not an admin.
Both of those downloads were made yesterday. I’ve got such post archives from a number of sites, but not all of them do I have uploaded images on. I have started to consider also archiving the images I have with the posts, and to do that I need to parse out the HTML. It would be helpful if Discourse would use a consistent format.
