Who told you to copy and paste posts? There have been numerous users doing what you were doing by copy and pasting but changing a few characters.
Sir I was new here and don't knew what to post so I read others posts and mixed two posts and replyed in the thread and I had know idea that copy and pasting was banned and I won't do it again so please if there's any way to unban my account please do it. It's all I have. Sir please unban my account!
If don't know what to post, it would have been better for you to learn rather than copying and pasting other peoples previous post.
You are not the first person to get banned and you will not be the last.
