Wiki Spam

I've noticed that Joi is setting up registration on his wiki to prevent WikiSpam. This is definitely one of those weaknesses of public wikis that everyone was aware of. I'm having the same problem on my wiki. Anyone else have any ideas on how to handle it? I might have to set up registration on my wiki if no one else has any solutions to suggest. It saddens me that I can't leave it open to the public at large.

You've got to love the irony...all the promise and potential of the internet, used by humanity to sell little, blue pills to each other. It's like what we did with the television, but somehow lazier, because now our computers just anaesthetize each other instead of getting us involved.
