Yeah, they're usually pretty good about the restores. I was deleting a bunch of characters that I don't play (< Level 5, and such). I accidentally deleted one of my mules which was holding a HUGE bank full of netherweave cloth. I sent out an email five minutes after I realized the error (which was about a minute after the deletion) and I had the character back in about fifteen minutes.

If I recall, this was like two weeks ago. Seems like an epidemic of foolish multiboxers.
