I notice that a large majority of the bots that publish articles to the wiki only post once. I bet that most of them aren’t equipped to deal with additional pages in the workflow, so I made a very simple new filter. All it does is check if an account has ever edited before:
user_editcount = 0
Then it just pops up a message that says, “Hi! I am glad you are editing the wiki. We pop up this message the first time someone edits the wiki, to throw off the spambots. But you, precious human, should just submit again and we will let ya on your way! ^_^”
So far it seems to be doing a good job so far.
