Why should we unban you?: i didnt know i was greifing because when i went to the big gated house i seen no one was there, my and my friend, Butterdtoast88 were running low on iron and there was no bed or anything in the house so we just took the iron, we are both sorry,
Why do you want to come back to WinterCrest: because it is a nice and quiet and calm server, also because the both of us enjoyed playing on the server very much, its nice and calm, and because i had just finished my house lol.
First off, grief is strictly against server rules and explicitly stated in the list of rules when you first joined the server. Surely if you had read the rules you would know this. Furthermore, I do not see why the lack of a bed in someone else's build gives you the permission to grief them. Even if a build looks abandoned, you can not grief it without explicit permission from the owner.
Secondly, you knowingly trespassed into someone else's build, break some blocks, and take their items, and yet can not make the connection that this is considered griefing?
Thirdly, you have done much more than steal a couple of iron blocks. You have also stolen redstone lamps and hoppers to name a few and killed animals that clearly belonged to another player. A lack of resources does not mean you can steal someone else's.
Given the inability to follow the rules, attempt to hide the extent and severity of the grief, and lack of effort in the appeal in general, your appeal has been denied.
