Every time I read something like this I see it as a clue there's a "secret" cult of AppStore reviewers getting paid by scammer to skip validation and just approve everything they're paid for. Prove me wrong, Tim Cook. If I make a clone app I'm banned. If a bunch of people do the very same app they get approved.
A customer paid us to white label it for their private internal use. The only difference between it and our existing app was the logo and color scheme. It was rejected for nonsensical reasons a couple times and then approved after several weeks. When we did the same for another customer, that app was rejected for different reasons and we were never able to overcome those objections. It was incredibly frustrating and cost our small company a ton of money.
