I am not exaggerating it. I stand by what I said. My comment has nothing to do with running actual crypto software, implying that you don't have to be running it to get your services wiped. You also don't have to be using the internet. The ultimate discretion is up to the mood of Hetzner staff and up to when they get around to seeing what you do. If the word "bitcoin" occurs more than randomly in your usage, expect it to be ended without warning. I don't believe it to be an automated process.
