I used to be a Hetzner customer for a few years (2018-2020), one day my card stopped working, while I tried to get a new one I ended up with a 5 EUR invoice, once I got a new card I tried to pay the invoice but they had blocked my account, so I had to transfer the money to their account to pay the invoice, once paid they told me to create a new account, I did and was asked for a picture of my passport after being a customer for years, I stopped trying to use their service at that moment. Now paying twice the price at Linode but at least they only ask for a phone number.
