@dansup interesting. You should possibly mention this to the developers (an edit may change the category contents). I'm more surprised by the lack of other tags, but I assume this is related? Or is Pixelfed not sending updated categories when hashtags change?
@oblomov Oh I see it did contain the sunrise hashtag at one point but was edited, that explains how Mastodon got that.
I was mindblown for a sec thinking they implemented object detection.
