XML sitemap discoverable

Priority 2 · Harden
DMARC policy enforces quarantine or reject
Observed: The DMARC policy for derpibooru.org was p=none, which asks receivers to take no action on failing mail.
What to do: Publish DMARC with p=none and a reporting address first, fix any legitimate senders that fail SPF or DKIM alignment, then move to quarantine and finally reject.
31% of Forums & Communities peers do this.

Priority 3 · Enable
Canonical URL declared

Priority 4 · Accelerate
HTTP/3 advertised
Observed: The homepage did not advertise HTTP/3 through an Alt-Svc header.

33% of Forums & Communities peers do this.
