When I search "Cloudflare MITM site:notabug.org", a fork appear above the original repository.
"Canonical link element" is important.
Please consider adding tag to the fork.
Forked repository (origin: /XXXX/YYYY) should have:
<link rel="canonical" href="https://notabug.org/XXXX/YYYY" />
Better would be to have each repository have a 'canonical' field in its settings, somewhere, that is by default blank or its parent(in case of fork) but which can be set.
