Forgejo is lightweight relative to some other options, but it is not resilient to scraping. Scrapers can access, commit-by-commit, each individual file, each file's "git blame", and each commit's repository archive... and they do. Most public Forgejo instances need to rely on a reverse proxy like Anubis or Iocaine in order to prevent server resources from being exhausted by bad actors. Or require sign-in for all access.
