@sb I've noticed similar accounts commenting on YouTube. They have been created years ago with minimal information, and suddenly they come out and go full throttle with pro-Russian arguments in debates on videos related to the US, EU and Ukraine. It's not ideal that Hetzner is hosting the email for them, but then again - if the Hetzner account is created by a EU citizen with Russian ties, it's almost impossible to detect.Personally I would contact the account owner and ask them a couple of follow-up questions and tell them to go elsewhere if I felt something was fishy.
