Kind regards Abuse team When told that they already have all the information in the original report, a human suddenly appears and replies that apparently every report needs to include a permission to be forwarded to the customer. Again, in the context of a clearly compromised box one would expect them to first block the box and then "follow up with the customer." Still, even with this permission and several hours in, the box is still spamming, customer is "investigating" and Hetzner has done all they could to handle this incident.
