Then i don't see any reason OP giving out his account to someone to make money, why not he uses the account for himself and then help his friend out with at least the little amount he could to support them than releasing his account. We know here we can't explain exactly how it happens since there is no forum for kind of free video calls or kind of kyc to always prove account owner.
Maybe theymos have to implement a verification processes for future purposes.
How do you imagine this would happen? Someone on the internet will be able to prove it to you by showing you their face, as well as the face of the person who committed the plagiarism. And that will be enough for you? Seriously?
I know this is not possible to happen here, but in terms of op conveying those wall of text trying to convince people around here how he gave his friend the account for financial assistance. Literally we can't expect such thing to happen in this forum, the op has to come with a clear evidence to prove that it was his friend because saying it wasn't him doesn't hold any strong and solidified meaning towards his ban.
