If anyone else did that on HN, they would be accused of slop with their domain blacklisted.
(Unless photos of actual pelicans count as "AI" content now.)
I just shipped this filter UI so you can see my other non-AI-tagged content in one place: https://simonwillison.net/search/?exclude.tag=ai
The "ai" tagged posts (2,100+) significantly outnumber "sighting" posts by orders of magnitude. Even searching HN, this post is the very first mention of it.
Perhaps that is why everyone here (except you) overlooks that or why we don't see much more of those sightings posts here either.
I would be very surprised if one of my sightings posts made it to Hacker News. Maybe if I manage to snap a photo of an actual pelican perched on a bicycle some time.
Knowing Simon - he’s very much both :)
