Just to be sure that this is not just a misunderstanding from your side and that you accidentally did "have more accounts", you're living alone and/or none of the person in your household ever create an account? Can you please check, suppose you're not living alone in your home.
No I doubt so. However. I do use vpn all the time but when I am about to login to KYC websites I always turn it off to avoid lock ups etc. I am not sure if that what triggered the “list your alts” thing but it don’t make sense at all. I think it’s just an excuse for them to keep my funds.
