We use Gravity Forms to collect our support tickets and Akismet to protect our site from spam in comments and the two work excellent most of the time with very very little false positives. The problem is that in our business a false positive means a missed email which translates into an angry customer.
I recently discovered a few emails from some clients in the spam folder of GF so the first thing I thought it was about the wonderful honeypot protection that GF uses and that many times saved me and my clients of receiving tons on spam messages so I went and disabled it for the support form. A few days later I checked again and a new message appeared in spam and then I remember that Akismet works in conjunction with GF to prevent spam.
So let’s see what happens from now on, I will let you know the results soon!
