Hi Gregg,
Thanks for the feedback, and I’m glad you like it.
I agree with you that it’s confusing. I was trying to stick with as much of WP’s core functionality and I haven’t yet found a way to exit as gracefully as I would like using a core hook. What I’ve done for now when it fails is erase the comment field and then hand control back to core so it fails there. I figured it is a good start since the comment spam robots wouldn’t really care about the message.
As I continue development, I’ll test out my own kill switch inside the plugin but I want to make sure that if I kill it there, I’m not leaving any unresolved issues elsewhere.
If it can exit without causing any other problems, I’ll be able to add a more user-friendly message.
The plugin updates should keep you posted on my progress but feel free to check in occasionally. Take care,
