The thing is that you were given the opportunity to appeal for an unban when you were banned for the first time so you could have simply apologized for using the cheat that got you banned but you took the decision to disrespect the unban request policy several times. In addition to that, you also got some innocent people in trouble by using their Steam IDs.
However, as you are assuming that you are willing to change your behaviour, I personally believe that you should be given a second chance. But I don't think that this should take place at the moment as you have shown disrespect to the community and caused a lot of trouble. In my opinion, you should be given a certain amount of time in order to redeem yourself and to give us a good image of yourself (3 months at least).
Good luck.
