Deutschlandticket fraud stemmed from decentralization and weak controls: tickets were issued instantly on unverified SEPA debits, and a leaked or mismanaged signing key let attackers mint valid tickets at scale. Poor revocation and fragmented verification meant many fraudulent tickets still scanned as valid, enabling mass resale and huge losses.
(edit: the fussy bit, where the poster complains about downvotes, has been edited out. I'm leaving my comment the way it is.)
Pretty simple. On my laptop the video fits 100% in the browser tab and there is no indication that there is more content under it. There is no text except the video title in the portion that I see when the page loads. And the link is marked [video] on HN.
So I simply closed it.
