Gotchas
Approval is instant but publication is not: the page they build answers HTTP 410 until the badge verifies, which is the same response a slug that never existed gives, so there is nothing to show for the submission until you deploy.
The badge snippet links to your own listing, and that URL is one of the 410s, so the badge points at a dead page for as long as it takes you to get back and verify.
They re-check verified badges on a schedule and say the followed links revert to nofollow the moment yours comes down, so this is a permanent fixture rather than a one-time hoop.
Verification flips the dashboard to LIVE before the public page catches up: for several minutes after the badge passed, the listing still served their "Tool removed" 410 while the dashboard claimed it was live. It does resolve, so check the public URL rather than the dashboard before telling anyone the page exists.
