If you want to increase the chances of being allowed to return, you should explain what you have contributed in the past. What benefit would there be to you being allowed to participate again? What benefit have others realized to your previous participation?
No, after seeing the number of posts that were actually being copied and paste then surely OP will straight ahead to walk out in this forum. Probably everyone here sees to it that there is no chance at all and the OP should not be given false hope that he/she might get his/her account back.
