After seeing people praise Kraken on reddit, I decided to give it a go. As soon as I created an account, kyc bs started to get annoying: their automated system just wouldn't accept my temporary residence permit (I'm a Russian citizen living in the EU). When I reached out to support, they told me that somehow that residence permit was not enough and now they needed to see my passport as well - despite the fact that usually wherever you go an id card is more than enough for identity verification, and they even mention a residence permit as an acceptable document on the website. What's even more concerning is the fact that a regular support employee apparently had access to the id I uploaded. I wouldn't be surprised to see user data leaked eventually.So in the end, I refused to send my passport photo, questioning their requirements, and that employee told me that he'd escalated my case to some dedicated team, and I should wait for them to reach out to me. A few days later my account was closed without any explanation.I'm not giving away more data than I legally have to, if you want to interpret kyc as "kill your customer", well, good luck staying in business.On the bright side, support was very responsive.
