Hi jhnpldng,
I’m sorry to hear you’re having issues with the plugin. I saw your other post on the WordFence forum and responded to that as well.
From what I read in your other forum post, it sounds like there are some hidden technical problems involved here that we need to help you fix or work around.
As of right now, for the Contact Form 7 messages there is no minimum length requirement (from WP-SpamShield). If WP-SpamShield blocks your submission, it will give you an error message that explains why. If you don’t get an error message, then it wasn’t the plugin that blocked it.
The plugin has over 100 different tests for spam, so trying to explain “what constitutes spam” here unfortunately just won’t be possible. It would pretty much require writing a book.
Let’s look into debugging the issue, and helping you find the solution.
Please take a few minutes to work through the Troubleshooting Guide and FAQs, as these solve 90% of issues users have.
If those don’t solve the issue for you, we’ll need a bit more info from you on the specifics, and we’ll need to email back and forth, so please head over to the WP-SpamShield Support Form (our main support channel), and take a moment to fill out a support request. That will allow us to take care of this as quickly as possible for you.
