Look, I'm not really one to criticize you for breaking rules--in some ways that would be hypocritical of me, considering harm I've done the server in the last month or so. But seriously, you have to realize that your actions affect people's perceptions of you. If you scam people 5 times, and the 6th time ask someone to trust you, do you think you're instantly trustworthy? You've demonstrated through your actions that your word means nothing, and it will continue to mean nothing until you prove it. I'm sure people are willing to give you a chance, if only you prove you're trustworthy enough.
Keep working, and don't be discouraged and become tempted to break the rules again.
