It is asked often How do I stop an individual user from seeing my ads on Facebook?

Maybe you are in a situation where a person keeps spamming the comment panels of your ads or keeps talking nonsense or doesn’t like you or your offer for whatever reason.

Since the hater is still engaging with your ad, Facebook is likely to keep showing him your ads.

Because the ad pixel doesn’t know what is actually going on. All it sees is engagement.

The solution is you ban him. First, hide his comment. Then you will see the button for the ban. That way he won’t see your ad ever again.
