OP, would an unban suit you, but if your signature space were locked, i.e. you could not have anything in your signature space for the next 5 years
They gave somewhat of an answer to that question in the other thread for second chances;
I do accept your terms of signature ban and will never ever repeat the mistakes again. You can also closely monitor me and you yourself can ban me anytime you think I'm violating any of the rules.
It didn't state that it could be up to 5 years, the duration on that thread is 2 years minus the amount of time spent banned. The key question for OP to answer is if you're not motivated to wear a signature why do you want to return to the forum? The answer to that will help give an idea of how the can be net positive to the forum or not.
