You are a good guy, your attitude, skills, and maturity seems fine, but there is one thing that is keeping you away from getting in. That is your loyalty, you don't seem loyal to us, the way you keep changing your mind, as WiLsOn mentioned before you were serious about joining DU, you were serious about joining almost every clan, that is clan hopping, that is something you shouldn't do. Hence, I'm voting no doubting your loyalty.
I will provide you on the things you need to work on, first of all, enough with the nicks man, too much nick changing you do, it makes you look dumb, still to one nick, Jean normally seems fine. The main part is your loyalty, I'd prefer you coming back after three months after getting denied and applying here. That's something which is enough to prove your loyalty to us, well this depends on others if they agree. About the rest, you are a great guy. Good luck!
