You Call Activision at 1800-225-6588. Wait for it to go through all the things and then say Live Agent
You will connected and be honest. Say you know what. I modded (Tell them if it was GPD modding), I was wrong, I didn't bother with the Enforcement Policy and I regret everything. Can you guys help me and tell me when my ban if it does expire and when. They will tell you to fill out a form or you can contact JD_2020 @ Twitter. Choose the form. Give all the info and dont hesitate. No further actions will be taken against your account for admitting you were wrong. Then within 24-72 Hours check your email and you should have a Time Frame of 24 hours to 2 weeks to forever depending on TreyArchs Decision and your Server Message on Black Ops will change and have a countdown. IF they tell you its perm (90 % chance it wont be unless its your second ban) then you tell them You know I really do apologize and if there can be any mercy. I will work a deal with you. Ban me from leader boards and Reset me for my access. They might take the deal depending on your tone with them.
Btw i never tried this my friend told me he did this today cause he thought of the idea,
I would try it but i do not have an Ban acc on black ops
I wish you all luck tho
