When I want to submit my question, system tells me "You can only ask 6 questions in a 24-hour period.", But I'm pretty sure I didn't asked any question in past 24 hours, not even in past 6 month.
I tried different IPs, even my real IP.
My profile just have one record for my questions. And I cleared any regarding cookies. But not any success, the system insist to not allowing me to submit my question.
