The best option for getting the most views and likes is to keep your page completely open, allowing replies to comments. This gets people talking about your content and sharing different media. However if your business is targeted by malicious commentators, you have privacy settings to fix the problem including blocking posts on a case-by-case basis.
Moderate Your Page
The 'Page Moderation' feature allows you to pick how to block comments or posts that contain certain phrases or keywords, e.g. if someone is constantly harassing your page, setting 'key words' will help you moderate comments. You can also set a filter on adult language using the 'Profanity Filter' settings.
