What matters on Facebook
Ad comments. Comments on a Facebook ad sit on the ad's post, not in your Page feed, so nobody scrolls past them. That is where spam does the most harm, because you are paying for every person who reads it. Check that ad comments are on the plan you are buying, not only the top tier.
Hiding by meaning, not by word. Spammers change their wording faster than you can update a list. A tool that reads what a comment means catches the new phrasing and leaves alone the customer whose question happens to contain a blocked word.
What happens to the rest. Most comments are not spam. Some are people asking about price, sizes or delivery. A tool that only hides leaves those for you to find; some tools also bring them to the top and help you answer.

Facebook's built-in tools
Before paying for anything: Facebook lets you hide or delete comments one at a time, turn on a profanity filter, and list words to hide automatically. For a small Page that is enough. Once comments outpace what you can read, or you run ads, a tool does the reading for you. Step by step: how to auto hide Facebook comments. Moderating Instagram too?

Frequently asked questions
What is the best Facebook comment moderation tool?
It depends on your size. ReplyMint suits brands that sell on Facebook and Instagram and starts free. CommentGuard suits Meta-only moderation priced by comment volume, from $29 a month. NapoleonCat suits teams that also want scheduling. Respondology, BrandBastion and Arwen are enterprise options with human moderators or managed services.

Can Facebook hide comments automatically without a tool?
Partly. In your Page's moderation settings you can turn on the profanity filter and list words to hide. Comments with those words are hidden as they arrive. It misses misspellings and new spam phrasing, and it can hide a real customer who uses a word on your list.
Is there a free Facebook comment moderation tool?
Facebook's own filters are free. ReplyMint has a free plan that flags spam and buyer comments and suggests replies; automatic hiding starts on Solo. CommentGuard and NapoleonCat offer free trials rather than free plans.
