While it is good that you found our security and server network to be up to your "testing", it is a criminal offence to attempt to hack any website even for ethical reasons without the website owners permission.
You could have caused damage to our systems or caused system outages, which is something we wouldn't appreciate.
You have admitted to the offence and this is a serious breach of our terms of service not to mention the law. After reviewing your account history, your account has been perma-banned.
