Ask HN: Apple won't let me sign up for the developer program. What do I do?

Here on HN, I have seen people say they had been "universally banned" from app stores due to the nature of previous work for clients. Basically, the behavior of those clients was linked to them either directly because their name was on the developer account or indirectly in some other way.

I don't know if or how any of that was fixed.

And I am not saying that's what happened here. Just saying that I've seen posts where people had similar issues that seem to trace back to previous work that the landlords apparently deemed problematic. Good luck.
