Blacklist Topics

Navigate to the "Optimize" tab on the right side of the document, and when accessing one of the topic menus from there, you can put your cursor over an individual Topic in the list, and there will be a red circle icon. Click this icon to blacklist that particular topic.

You can click "Blacklist" in the dropdown menu in the Optimize tab to see these blacklisted topics, with the option to add them back to the list by clicking the green checkmark.
