Well just to add something on top of it,
Hetzner doesnt even offer Crypto payments to pay the invoice/rent hosting.
So chipmixer used a provider who resells the server of hetzner which means that that this " middleman " provider could snoop around aswell and as also a security breach itself on top of that!
I dont want to make false conclusions but the operators of CM didnt even made an own based research hosting wise.
