Spam Trap for Contact Form 7

This plugin adds spam checks to catch contact form 7 spam. It does so in the background without annoying your legitimate users with captchas. Simply install and activate. Optionally set limits for how many links you’ll allow in a comment and set up email notices of blocked or allowed form entries (useful for test and evaluation)

1.0.0

• Initial version

1.0.1

• Fixed bugs in saving settings.
• Added message field name to change which field is filtered in the contact form 7 form.
• Changed filter to work in the skip_mail filter rather than the before send action because in before send the skip_mail property has been made private so we can’t set it if needs be

1.0.2

• Checks for blank messages and counts as spam if found. This is because spammers are now putting their message into the subject and leaving the message blank

1.0.3

• We were filter_santizing_string’ing the CF7 message before counting links. The problem is that if there are spammy links like example then the filter_var removes those and they’re not counted (not present)

• Added an icon to the assets directory
