Apple’s terms explicitly prohibit using automated tools to scrape or analyze App Store data, even if it’s done outside an app. When they flag something like that, they usually don’t explain the reason — partly because they don’t want to expose how they evaluate developer activity or link accounts to external projects.

Not saying it’s definitely the cause, but it’s one plausible explanation the author was denied.
