Real DMARC damage

Am I the only IETF list admin who's had to deal with genuine DMARC damage today?

gen-art(_at_)ietf(_dot_)org had four subscriptions suspended for excessive 
bounces, all caused
by mail from one participant whose sending domain has published a p=reject 
policy

Bizarrely, one of the subscriptions disabled was @gmane.org. It's a very strange
choice for them to respect p=reject.
