I'm a happy user of Forgejo and I host it on my homelab at git.sitegui.dev to store all my open source code (including this very same page).
However, as many other hobbyists and major projects, I have noticed an uptick in the number of crawling requests that my instance serves. My homelab is literally an old laptop close to the fridge, so I could hear the extra load (and it also doesn't help that Europe is scalding with 16 degrees above average temperatures for May).
I saw an increase from an average of 1 000 requests a day to 200 000. The issue is not only the number of requests, but their nature: these bots go over the whole git history to navigate the whole tree of files for each commit. They also request a lot of repo archives that are expensive to generate.
The robots.txt clearly forbids bots to navigate to these pages:
User-agent: *
Disallow: /*/*/src/
Disallow: /*/*/archive/
