I wonder what the internals of the App Store process are. For most app approval processes you can tell because you'll get connections from the Philippines etc. so I assume what's going on here is that these reviewers have a range of English proficiency with a median below what an American developer is used to. Then the rest is just hallucination from the human, guessing at what they're looking at.

All of my app review submissions come back at like 2-3am, so yeah.

We had a client whose website geoblocked non-US IPs and failed several rounds of review until we gave up and put a copy of their privacy policy on S3.
