I've created a "giveaway" post type and launched couple times of Giveaway campaigns on my website with default comment system by this plugin: https://wordpress.org/plugins/pick-giveaway-winner/
This plugin randomly draft users who commentted below in a giveaway post. In my case, I asked the participants to leave their phone number for contacting. Here comes a problem when I modifying my theme recently. I am considering to turn on "Recent Comments" widget in the sidebar, however, it expose their personal information.
Is there any method for me to create exclusive comment system for my giveaway custom post type?
