Hi HostColor, Sorry for just now replying to your post. I'm a new member. We at Hetzner Online take spam and any other abuse very seriously. If you see spam coming from one of our customer's servers, please fill out an official abuse report:
https://abuse.hetzner.de/issues/new?lang=en. This will allow our abuse team to handle the situation in a legally binding way. When you send the form, you will immediately receive a mail from our abuse team with an abuse ID. You can then respond to this mail if you need to give us further information.
We hate spame as much as you do, but it is difficult for our team to act in a legally binding way unless someone sends us an official complaint. That being said, we know that abuse forms at any provider aren't especially fun to fill out. So we truly appreciate you taking the time to do them. Thank you very much in advance! --Katie, Marketing, Hetzner Online
