that one customer who is genuinely being an asshat

Tarsnap sometimes has "problem customers", but I have yet to see one who is trying to be a problem. It's not really the customer's fault if they don't know how to install a compiler, think that uploading 100 GB over a 512 kbps cable modem will only take a few hours, or can't figure out how to enter a valid tar command (cue xkcd).

I do my best to help such customers, which usually involves refunding their money and pointing them in the direction of dropbox, spideroak, or duplicity.
