I ran into a problem where the Akismet spam filter is validating the Firstname text field, but not the Lastname one.
Here is how I have it set up:
[text* firstname akismet:author]
[text* lastname akismet:author]
It works fine when I typed "viagra-test-123" in the Firstname text field and just random text for Lastname field. But it didn't catch it when it is the other way around.
Anyone knows why? Or how to fix this?
