Was she tried before a competent judge? Or before a jury of her peers?
Yes, on both counts. We all bent over backwards to try to help her become a useful contributor and gave her every opportunity to state her side of the case. But in the end, her peers concluded that she was more a hindrance to the project than a help, and our judge did what was necessary to get our work done.
And I disagree that short bans of 2 days or so are of any use; this isn't a punishment, really. We're not just issuing a slap on the wrist and saying "don't do that"--we've already done that ad nauseam for a long time now. She's already gotten any message there was for her to get. The ban is a practical measure to allow the rest of us to simply edit articles without having to waste any more time cleaning up her messes. That's not useful unless it's for a reasonable period of time.
