? Yes? Toomuchtodo is reminding the author (and other commenters), that github gists are one way to make sure secrets are secured / remediated before making a public post like this. Maybe not the most responsible whitehat action, but I can see it being useful in some cases where outreach is impractical / has failed.

Unfortunately, it doesn't look like Algolia has implemented this

I'm not following this at all. It seems like OP is saying if you share a secret in your (private?) gist and give Algolia permission to read the gist, they will invalidate it. But why would the secret be in a gist and not a repo? Also if you're aware enough to add that partner it seems you're aware to not do dumb things like that in the first place.
