Sometimes new articles, or editors, are marked as “patrolled.” If you get this message, don't panic. Though the language sounds a bit severe, it's actually a good thing. It means that an experienced Wikipedian has come by and checked over your work. Marking the page as “patrolled” lets other editors know that you aren't a vandal, or a spam-bot.

If your page isn't marked as “patrolled,” don't worry, either. It's a random process and there are thousands of articles to review, so it may not happen quickly, or ever.

Basically: it's not something you need to worry about either way.
