Something is happening right now at Apple, as I have seen another post on reddit about that (could not find it), where people complained about their Dev Accounts were banned as well, when they even did not have any apps, just used dev accounts to notarize apps for themselves.

It does suck, A LOT

While notarization as method of increasing security is a pain, I guess we need more details. For all we know, it is just as likely that some bad actor was prevented from distributing notarized apps. Perhaps even the developer was unaware that their machine has been compromised.
