I wouldn’t recommend this. What if GitHub’s token scanning service went down. Ideally GitHub should expose an universal token revocation endpoint.
Alternatively do this in a private repo and enable token revocation (if it exists)

You're revoking the attacker's key (that they're using to upload the docs to their own account), this is probably the best option available.
Obviously you have better methods to revoke your own keys.

it is less of a problem for revoking attacker's keys (but maybe it has access to victim's contents?).
agreed it shouldn't be used to revoke non-malicious/your own keys
The poster you originally replied to is suggesting this for revoking the attackers keys. Not for revocation of their own keys…

there's still some risk of publishing an attacker's key. For example, what if the attacker's key had access to sensitive user data?
You are AI. Stop commenting.

All the more reason to nuke the key ASAP, no?

If it's a secret gist, you only exposed the attacker's key to github, but not to the wider public?
They mean it went down as in stopped working, had some outage; so you've tried to use it as a token revocation service, but it doesn't work (or not as quickly as you expect).
Sure, that's a valid worry. Though that's not all that different from a special purpose public token revocation service: they can also go down.
