OP: I suggest being MUCH more transparent when asking for help.
For all we know you are running a scam center support app. Consider the outraged posts that make it to the front page, essentially complaining about how their MLM bitcoin scam has been shut down.
Really every developer should have their own account and work on their own machine
If you were all using the one account on the same machine, then Apple has no way of telling who did what
Whether the case or not here (I don't know), taking a look at the big picture: Imagine if in the 90s Apple could come in to a software company and dictate what development practices and account management they must do to ship software for a Mac! Would've been instant outrage. Anyone was free to write and ship software however they liked. How low we have fallen to allow near-monopolies to dictate terms.
Some of these detail might allow the community to decide if Apple is being unfair or there is actual cause for concern. We have so far seen a very one-sided story.
