After the recent vandal attack on zh:, I have written a bot to enable faster deletion of pages. Basically, it shows each page in a list, and asks one whether to delete it. Because of the contentious nature of the bot, I prefer not to give out the code freely (although it is actually very simple), but trusted users with some experience in large-scale vandalism repair can ask for it.
Note that this bot is meant to be used ONLY in cases of large-scale vandalism, NOT for normal deletion.
Also note that Tim is fully correct in stating that a developer could do things even easier.
