It's not the raiders responsibility to make sure you don't repaste, it's your responsibility to check if you can repaste. If the staff members told you to repaste and if they were not present at the situation, they have no right to say repaste. I do not know how it was, but that's just how I see it. If they did tell you to repaste though and no one was raiding while you got told this.
I was not present therefore I can't tell wether it was appropriate or not. I would handle this, but you prefer an SA to do it.
Overall Jenga. You know your loopholes and how to use them correctly, trying to escape every sit with them. If you had recents (7+) this ban is well deserved.
