Totally unprofessional and a complete joke. Will never use them on a production system again. Always angry if they are mentioned here like they are a legitimate choice...
That said, with Hetzner I've had the trademark complaints as well, but they've always given us 24h, and were always okay with us saying that our usage (e.g. showing a logo of a shop next to their review) was fair use.
I have an email from them forwarded by a third party reporting phishing on a CF-DNS-hosted site where Cloudflare denied they had any responsibility whatsoever as “they host no content”.
Of course, it requires a subpoena to discover who DOES host the content, as they are the only ones who know.
