Facebook offers you settings on your business Facebook page that enable you to mute offensive words. I suggest you check k your settings and ensure they are what you want for comments on your business Facebook page.
I saw a post recently where a business promoted new products just arrived in-store. Someone commented that they liked them and in one sentence used the ‘F’ word. They meant it in an excited / happy way whereas others reading it could see it as a swear.
With the right Facebook settings the ‘F’ word would never make it as a comment, thereby reducing the opportunity for someone else’s comment offending a reader who could be your customer.
