According to Google Support's "Dangerous Products or Services" page, the company "[wants] to keep people safe both online and offline, so [they] won't allow the promotion of some products or services that cause damage, harm, or injury."
Included in the dangerous products for which ads will be blocked are "Guns & Parts." This covers "functional devices that appear to discharge a projectile at high velocity, whether for sport, self-defense, or combat."
Also included is a ban on ads for "any part or component that's necessary to the function of a gun or intended for attachment to a gun." This covers "gun scopes, ammunition, ammunition clips or belts."
The ban will also halt ads for "dangerous knives... throwing stars, brass knuckles, [and] crossbows," among other things.
Google Support says the ads that will be banned "are subject to change."
