Last year I sent a €5k transfer to my Paysera account from another personal account (both accounts are in my name) and they put the transfer on hold and started asking all the stupid stuff about how I got this €5k.
After 2 weeks of emails (their ETA for responses is no less than 2~3 days) of sending documents and responding thoroughly to emails, I asked them to refund the transfer and close the account. This also took another 2 weeks of calls and emails.
To give you an idea of how funny/stupid their system is, I transferred €1 from the main account to the card account, and they put it on hold for review. It was released the next day. Just 1 euro.
At the beginning of the Russian/Ukraine thing, They sent an email to all Paysera users saying that they would close all accounts of Russian passport holders and place their money on hold "Until further investigation", even if you were not a resident of Russia. The decision came into effect immediately, and all money in these accounts was frozen. God knows if they released it yet or not.
The fact that you hold a Russian passport means you're a bad person and acting as the right hand for Putin. just some woke culture in the banking system. I was not affected because I'm not Russian, but I despise the injustice committed against someone simply because of where he was born. and not only closed the accounts but also frozen the money, which might be life-or-death emergency money for someone.
Remember friend: It's all good until it's not good.
