I've pushed a token reference to github and already runned a rebase do delete the commit. The commit were removed but the old file still acessible by URL from pull request merged weeks ago: https://github.com/mycompany/myrepo/blob/30ba903ea69be04a8619a8b3893a782a634f7118/path/to/file.js#L14 .
Is possible to delete this entire "blob"? I don't want to let it acessible.
