- Every product/project you manage should be on a separate account on Google, Facebook, Amazon, etc.
- Nothing tied to your consumer accounts should be used for anything business related.
- Your Amazon shopping account and your AWS account should definitely not be the same account.
- Don't use services where you're required to mix accounts like this.
Some examples:
- If the issue in this thread is actually an automatic ban, account siloing very likely would have avoided the issue. ([edit] likely, it would not have been possible to silo accounts in this case, as a child comment points out)
- Facebook apparently lacks the willingness to block an account from Marketplace, but they will block an account from all Facebook properties.
- Paypal has banned businesses because the account was created years ago by someone who at the time the account was created was 17.
The point of this isn't that it's impossible to connect the dots that you are the same person. The point is to make it difficult for an automated system to deal too much damage to you, and make it difficult for someone looking at a single account's history from accumulating too many "strikes" against that account.
