If someone in a non-restricted country fills out KYC (your mule) and is confronted with evidence of logging from a restricted country, they simply say "I was travelling and logged in at a friend's house".
If they say "you are using a different device", the mule says "I got another phone" or something reasonable.
Just have your story ready. But be prepared for the mule to take all your funds, or demand more than you initially bargain for. In which case, you could consider asking for collateral, though the mule might then think they are being scammed.
Just use common sense, plan and rehearse.
Ha, didn't know the other person is called a "mule." But yes, I was thinking about this. Technically I can come up with some clever rebuttal I can feed to my mule counter to all their accusations and there is no way for them to disprove it. But in the end I think they will simply give me some BS automated reply saying I broke ToS.
Also, can't I simply get KYC docs from my mule and submit them myself? My mule would not even need access to the account. But the mule must have trust in me to be dealing with their personal info, and a promise to receive payment.
Anyway, it all seems like too much of a hassle and the odds seemed stacked against me. Learned my lesson here.
