Is the Grief located in the Wild? If so, is there a pending Mayor application for this defined region?
Nope.

Co-ordinates of Grief:
-90 63 11458 (That's one of the blocks. In that whole spawn area she destroyed all the gold blocks and replaced them for wool and sandstone).
She also destroyed a purpur block.
-89 58 11458

Brief Description:
She griefed all the gold blocks in the "spawn" of the town. She also griefed a purpur block.

Update: She killed 6-7 chickens. In the town it's against the rules to kill chickens with nametags.

She also placed random obsidian in front of people's doors.

Which users own the griefed area, or are allowed to edit blocks in the area:
The only thing on plots were obsidian in front of doors. The rest of the grief was in the "spawn" area, which is only allowed to be edited by the mayor and comayors.

Screenshots to assist Staff identify the grief:
I would provide screenshots, but for some reason I can't save screenshots right now.

Rollback Request:
I would, except I'm sure the items aren't worth 7.5k+, so, unfortunately no.
