I don't know, does this forum has a rule that states that we can lend or rent or even borrow out our account to friends?
Rules don't allow things, rules prohibit things. But there is no such rule.
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 has to implement a verification processes for future purposes.
