My neo-bank (Revolut) has this feature. If someone sends me money for the first time, or isn't in my contacts, they have to explicitly accept it from their app before it actually lands in their account.

Ignoring that specific feature, if you did get money sent to your traditional bank account, you can always contact your bank and tell them you don't know what it is to avoid any trouble. This is not possible with Ethereum.
