It is not for me to say what the global mod or the admin will decide about your ban, but I will say that in your specific case there was more than an obvious intention to incorporate someone else's work into your posts. You started your posts with the original content, and then you add plagiarized content, which is one of the worst ways to plagiarize - except maybe those that also use word spinning.
A signature ban in my case would be mercy. I will accept such mercy if given. Being a member of the forum is more important to me
Everyone deserves a second chance, and many have got it - so I see no reason why that chance should not be given in this case with the signature ban.
