Excellent plugin, thank you for making it, it’s helping me curb the sudden onslaught of spam coming through Contact Form 7.
Quick question: Can you confirm that CAPTCHA WILL accept code the visitor types in lower-case letters (so “QZ7U” can be typed as “qz7u”) but WILL NOT accept code with added spaces to match spaces the visitor perceives in the code (so “QZ7U” can’t be typed as “Q Z 7 U”)?
I want to add instructions to my visitor on how to enter the code so it’s accepted on the first try, just want to be sure those instructions are correct.
Any other restrictions or allowances on how codes can be entered that would be helpful for visitors to know?
