Twice in the past two days I've requested cleanup of objects from sandboxes that either make the sandbox unusable for everyone else, or threaten the stability of the sandbox sim itself.
And each time, Mia Linden responded so quickly that she was there, cleaned up the problem and gone almost before I realized she was there. When I did catch up to her to thank her, she was courteous and professional to the Nth degree.
I hope you guys are working on cloning her, because she's the best!
