I saw their post saying that too, and they also PM'd me the same thing. Their screenshot shows that they bought it during the time that I said it was hacked: Sometime after May 2017, before September 2017. They say they bought it in August of 2017.
I have given complete proof that the "Delicieuxz" account is mine. You linking to a thread in which the site owner states their preferred way (because it's the quickest) of proving ownership of an account doesn't mean that all other proof is somehow not proof. I have given full proof that I am the owner of the account, by showing that the post history of the account is mine, and mentions my own crypto currency accounts from other sites, which I've shown myself logging into in the videos I uploaded.
Additionally, the person currently using my "Delicieuxz" account has confessed that it isn't their account, and that they bought it from a hacker.
