He was banned because he told mods/ ops persistently to fix grief, even though he made all of the changes himself. Calling a false alarm once is not a big deal-- PERSISTENTLY calling mods/ ops for false grief IS a big deal and he kept on spamming the false alarm.
I think that's reason enough for his ban, and he has been banned himself a couple times after that for griefing grieftraps. Obviously he doesn't know what constitutes grief, nor does he respect other staff members. WE CAN READ ALL BLOCK HISTORY.
In light of my rant, wait for benwin to respond, although by that time I think that the ban will reserve, since the ban lifts at some time today.
