You were actually banned because i watched you steal another players gold blocks after i had warned you for griefing/crop griefing.
The logs also showed you as having made very few, if any constructive edits.
(please see screenshot evidence below)
The punishment is a 1 week ban, since you were banned 3 days ago you will be unbanned on Sunday 10th March.
I suggest you familiarise yourself with our rules before rejoining. https://nerd.nu/rules/#pve
