Wait, maybe some users of Happymod try to use PayPal to make transactions related to these modified apps. Perhaps they might want to pay for something on Happymod using PayPal. Is PayPal associated with Happymod at all? I don't think so. PayPal is usually for legitimate transactions, while Happymod is on the gray or illegal side. So the user might be asking about the legitimacy of using PayPal with Happymod, or maybe the risks involved.
