I'm not too familiar with the Wiki software other than wikipedia but surely you could use a system similar to name server registrations and other sites where you have to type a graphically displayed code that can't be read by bots but can be by humans. No user/password required just that you're a human sitting at a PC.

I think where software gets deluged in ways such as this the primary fault is the software design not the spammers that abuse it.

People in enough numbers will abuse anything if it's open to them. It's up to the industry to stop it from being possible rather than chasing or deterring the culprits because you'll never get them all and the idiots are multiplying every day.
