I've just noticed that an anonymous monk seems to have created a whole load of empty nodes. I know it can be easy to create an empty node but they are quite annoying. As an empty node contains no information shouldn't there be a simple filter to prevent them from being generated? eg. if the body of the post is empty then reject the post and return error message.
Also another/the same(?) AM has created a load of what appear to be useless nodes in every category (code/snippets/discussion etc). This leads me to ask, and I'm sure I'm not the first, if this sort of thing happens should AMs be allowed to post?
