Hell-banning is by far my biggest fear with Google. The idea that you could be banned for life without any explanation just seems completely insane. It feels dystopian.
A couple of direct recommendations to combat this fear.
1. Sales teams can help here. You have a sales rep that you should meet/interact with so that if something like were to happen, you have a person you can reach out to. There has been a lot of news about hiring within sales.
2. Set up a proper Cloud Identity domain and organization. Manage users this way as opposed to consumer accounts.
