Google associates different accounts that are from the same owner when handling issues FYI. So if they think your account is doing something wrong on GCP, be wary of associated accounts.
Separating concerns, isolating things that are not related, these are some basic tenets of good engineering. Yet we all keep rolling the ball of mud downhill and act shocked it keeps growing and swallowing everything.
I might be paranoid, but I just don't feel comfortable when there's so much in play.
