+1 I don't think it's fair to bring up the exploiting situation. Please keep in mind what he's done prior to the exploit. He's made some amazing builds that have an embedded atmosphere that you can't find from other builds usually.
I was involved in the situation, I tested if it worked and was on a call with them as it was happening, it's human nature to want to one-up your situation, and as Lui stated, he barely participated in it. Another player I won't name was the huge anchor in what was happening and as a result, others got dragged down along with him.
I've done the exploit, and I've received trusted afterwards especially after management knowing I was involved. You're entirely welcome to judge from the perspective of: "He exploited, I don't trust him", but if you dig deeper you'll uncover he's an amazing bloke and the situation was very complicated.
As a result of the exploit, he lost more money than he gained (which was nothing, as the response time was very quick), and I could tell it hit hard. I was honestly surprised he came back because he's essentially played with a blacklist and dealt with the consequences for a while, which shows his love towards the community.
He's an active member in the community and he's offered his services all the time within the server, an example of someone utilising their skills and garnering enough trust to where he makes money off of building for others.
If he messes up again, the simple solution is to just permanently ban him. People change, you live and you learn.
Thanks to whoever read my reply, Gretta is a good bloke and I hope he gets the chance to redeem himself.
