I grief-ed By accident

there's a Castle that has water flowing out the top and may have grief out through  a portal i am sorry and looking to repair damage or even donate for the castle (had a sign)

I just don't want ban due to a ghast about to kill me in the nether it was a close portal so i made a break for it

You know, instead of taking 10 to 20 seconds in using that portal you could immediately escape using /home or /spawn.
