They are physically deleted or marked as deleted (see below). There is
no reliable way for Extbase to determine whether an arbitrary object is
referenced by another object or not. TYPO3 has a reference index, but I
would not rely on it when it comes to delete a bank account of a
customer ;-).

You can use @cascade remove for that if you control your domain (=know
what's related to what). You can also remove related objects within the
repository.

Extbase uses the standard TYPO3 mechanism. If you define a deleted flag column like

'delete'   => 'deleted',

in your TCA, only a flag is set. If not, it gets physically deleted.
