And they want a customer who will rent the dedicated box for a long time and not wipe it after every 2$/2h Trialcustomer

same problem, credit card fraud/chargebacks happening anyway, that’s why you have an intense verification process to reduce the fraud going on.

You can do that with Hetzner virtual (cloud) servers, just not with dedicated servers.

You're basically describing the internet-scumbag use pattern - bounce around providers and servers using nothing for more than a few hours at a time and making tiny charges to (other people's) credit cards that won't trip fraud controls because they look like verification charges.

There are very very many reasons to prohibit exactly that type of usage pattern.
