No, the KYC trail is there. Coinjoin doesn't help shit for that 

 Yup 

 Coinjoin is forward privacy.  

 Curious to know what you mean by forward privacy 

 They still know how much you bought and will hold you responsible for it. 

 But you lost the keys or it was hacked and stolen.  

 Pretty sure the response would be “NOP (not our problem)” 

 …and the thief seems to have coinjoined my whole wallet… 😭
