OK I take that back. I count 30 edits per minute not 100, which is pretty typical for a page blanking spree with just a browser. So that means the vandal is probably more bored and mischievious than depraved.
I was watching the recent changes IRC room. The edits were flooding the room at times, then the bot was stopping, then flooding again. I imagine it was actually a bot doing it, not a human, and obviously it was blocked quickly. It was going at a rapid rate, too fast for a browser user.
that's quite consistent with someone loading some edit pages in browser tabs, submitting them all at once, and then loading a few more. i've done it before myself, though for slightly more legitimite purposes...
