Went ahead to read the reputation but you cheat which is something so serious here and the individual who gave the feedback is someone who doesn't do that without some real evidence. My advice, you don't need to have open the thread because its a personal matter that only him can remove when he feels that you have really change and proving that is not going to be easy. Be ready. I have seen people open thread to talk about their negative trust and instead to get it removed, they got increasing one which makes it much more difficult to resolve. In this case, rather than convincing @ThePharmacist alone, you have to battle with convincing others.
