39
+
40
+ Note: When an entry is marked as Spam, it also prevents use of the configured confirmation. Users submitted a entry marked as Spam will see the default Gravity Forms “Thanks for contacting us! We will get in touch with you shortly.” confirmation text instead.

75

76

77

78
+ `add_filter( 'gf_zero_spam_check_key_field', '__return_false' );`

+
82
+ 1. Go to the form

84
+ 3. Under Form Options, enable "Prevent spam using Gravity Forms Zero Spam". _Don't see the setting? This feature requires Gravity Forms 2.5 or newer._
