In Meta Ads, we can block visitors from seeing your ads by adding them to a custom audience, and then excluding that audience from your ad sets by updating their targeting specifications.

During account initialization, ClickGUARD creates a new custom audience where we'll be collecting all the bad visitors, and we can automatically exclude this audience on all your ad sets.

When an ad click triggers one of the rules in our system, we are sending and event to Meta Ads to identify the visitor and add them to the custom audience. Since the audience is already excluded, this means that the visitor will automatically be blocked from seeing your ads in the future.
