You've had your "one chance" - two of your alts are banned, so you are guilty of ban evasion:

"Sir, you are absolutely right. I have had two of my accounts banned as I was not aware of the rules before. Now I have learned the rules and will follow them. I hope that you, as senior members, will consider my case favorably. When my account was banned in Cat1, I used this 'qurbanshah' account, which was not mine but belonged to my friend. Now I am using this account and I hope that you can verify my previous posts. My friend had deactivated this account, and I started using it just a week ago. I have only used one account at a time, and if I have made any mistakes, I sincerely apologize. I request for one more chance."
