So, yes, this appears to be all fraud or unreliable sellers. Not the AliExpress store, but the sellers. I have ordered 10 miners a few days ago and today I have received an email from Ali:
Your Order No:608185xxxx3115 has been closed because the supplier did not provide necessary evidence. The payment will be refunded to you within 7-10 working days.
AliExpress strives to continuously improve our trading environment. Thank you for your understanding and continued support.
Sincerely,
AliExpress Trade Security Department
