That's my personal self-hosted feed reader. If you found
feedsd/<version> (+https://go.guillerg.dev/feeds)
in your access logs, I probably follow your feed.
I aim for feeds to adhere to best practices (conditional GETs, one request at a time per host, etc) to
avoid overloading your server. It will honour headers like Cache-Control: max-age and
Retry-After as long as they're sensible values (up to 24h).
Besides your feed, I occasionally request your site's icon and, once per article, the first bytes of the lead image if it has no declared size.
For questions or complaints, contact me via the socials or email linked in my personal site.
