Any documentation is good. What is this 'spam'? Haven't personally encountered anything on the wiki that would be 'considered' spam (perhaps not stumbled upon that portion?)
But it's inevitable that the wiki will be attacked by unscrupulous people and as such, the wiki should prepare for this. The wiki is going to need gatekeepers/admins to maintain it. It would be nice, that any edits be archived so users can see previous states of the page if they so choose so. If a noted jerk keeps editing the wiki, we should have a system that only applies his edits to his account. The common user would not see his edits, only he would, which would hopefully convince him that his edit has gone through. +1 top hats.
