I knew they (and most other) cloud and VPS hosting were banning mining, ... that's been the case for a decade even, ... but I didn't think simply running a node would be against their terms of service.

Lots of Core nodes and LN nodes are run on AWS, etc., and some are even on Hetzner. [I know, ... that's terrible for privacy and security, but I'm just stating facts.]

I wonder if this action by Hetzner was selective enforcement because it was a privacy coin (Monero)?
