How can I trigger Mollom to detect a form submission as spam?

I am testing a form using the Mollom Drupal module. I have tried submitting some posts that I thought would trip the spam filter (using the word "viagara" repeatedly), but it didn't catch them. How can I trigger the spam filter for testing pur开发者_StackOverflow社区poses?

Mollom has a developer mode. Check out the How do I test Mollom? page and the Testing Mollom without damaging your reputation page.
