Unlocking GDPR Secrets: What Every Author Must Know Now Before It’s Too Late
The problem is that as soon as somebody uses your Contact form again, another entry will go into your WordPress database, and you can’t prevent it. (Gravity Forms doesn’t give you the option of not saving those entries.)

The plugin is called Wider Gravity Forms Stop Entries. It’s free and you can find it on this page on the official WordPress plugin site. I installed it today on my site and it seems to work well.
