Checked your post history quality — seems like you're not the type of user where Theymos might give a second chance because of some sort of post-quality redemption ark. I honestly don't see anything of quality. Sorry bud.
LoL, a bitter truth, but it may look discouraging to the OP.
OP, I really cannot tell why you wait so long to appeal for your banned account, probably for reasons best known to you, but you should know better that plagiarism is a case that is not taken so likely in the forum.
If you really feel that you could be forgiven, then I wish you luck. Often times, people make mistake and get punished just as you got banned. At least you have learned a good lesson, so if the ban gets lifted, you will only use your account when you are in the right state of mind. You could also write more reasons why you think your account should be given a second chance and what lead you to commiting plagerism.
