To show you can push to seed4j/seed4j, add a file named .favz-claim at the top
of its default branch, holding this line:
favz-claim-1791102018-be8e416f65942d16541a88dc
Then press Check. A pull request works too, once someone who can push merges it.
The code works for 7 days; keep this page or come back with the same link and a new code. We read the file once through GitHub's public API and keep the repo, the GitHub login of whoever committed the file, and the date. Delete the file after. You don't need to claim a repo to get it off Favz: ask for removal, no proof needed.
