That defeats the whole "anyone may edit" part of what makes wikis what they are. Yes, communities may lapse into inactivity on account of any number of reasons, and yes, vandals may show up and disturb unmonitored content, but if you forbid potential good faith contributors from making positive changes, you might as well just remove the wiki altogether. There is always room for improvement on any wiki, even those dedicated to niche subjects.
