I think something you guys forgot to mention is: He admit what he did. And from what I know, this is very positive, even if it's not about cheating.
I do also belive, that he didn't know about the banevading issue, as I didn't knew it either when I joined ambrosia first, and a mate of me got banned. I hope the unban panel can consider these 2 points I've mentioned.
Off..
An admin should be taking screenshots to make the unbanprocess go faster. Logs would take a bit longer to check, so an admin should if he can take evidence. But ofc, in case he hasn't made a screenshot, logs can always be checked. But I don't see the point why you guys argue with each other for such a stupid thing, as both are saying the same thing, only in diffrent ways.
