Even then, they are also often quite quickly revoked, due to a combination of people sending a deluge of server requests (Mostly for flexing their strong verdicts, which they probably didn't need anyway... You know who you are) and Google [deploying specialised crawlers](https://developers.google.com/search/docs/crawling-indexing/google-special-case-crawlers#google-safety) for detecting said keyboxes. You'll know you're using a revoked keybox when you're only passing `MEETS_BASIC_INTEGRITY`, at which point you'll need to find another to return to Strong Integrity, or use the publicly available AOSP keybox/just remove TrickyStore to return to Device Integrity
