One issue is that even mailing lists that have only confirmed opt-in subscriptions can contain spam-trap email addresses, where previously legitimate email addresses were after a time of non-use repurposed as spam-traps. The general advice to counter that problem is that mailing lists should reasonably aggressively remove bouncing email addresses. This advice is however problematic for those mailing lists which, e.g. due to the subject matter, relatively often generate bounces from spam filtering false positives, as those can be difficult or impossible to distinguish from bad email address bounces in a fully-automated and yet reliable way.
