It would be interesting if someone wrote a worm that just took all the vulnerable rails apps offline. That way we would have less worry about a million compromised databases. It could be launched from a bookmarklet run from tor browser, and would probably exhaust every ip address in a few days. It would also land whoever did it in jail for a really long time.
Maybe, though with today's legal climate such a thing would be extremely, extremely risky. Gaining unauthorized access to a computer system and exploiting it in a way that potentially causes loss of revenue is not something you want to do lightly even if it might be the right thing to do.
