If the reason for you wanting to have the account ban lifted is because you want to contribute to the forum, you could have been doing it for the past five years of the duration of the ban. Based on that, I do not believe you and add to that the fact you were wearing the signature/avatar of the campaign that probably has the most problems with signature spam, things become a little clearer.
What is the real reason you want the ban lifted because it is not because you want to contribute positively.
Yes, I'm more than willing to accept the signature ban. I do not just want to earn money from this forum but want to do something constructive which matters.
My account will anyways be worthless if the signature space is locked but it will allow me to start posting & contributing again.
