Fifty-eight people were killed in the Las Vegas massacre last week, the deadliest mass shooting in modern USA history.
The video sharing site deleted content explaining how to make guns fire more rapidly using a device called a "bump stock" following the news that Stephen Paddock had converted his weapon in this way. The videos recently disappeared from the service, and the guidelines were updated alongside this to reflect the new restriction.
Ahead of YouTube's recent ban on bump stock videos, the company's guidelines prohibited "content that intends to incite violence or encourage unsafe or illegal activities that have an inherent risk of serious physical harm or death".
YouTube will now ban videos that show viewers how to make guns deadlier than they already are. Paddock had used the bump stock device to make his rifle fire like an automatic weapon.
This announcement by YouTube comes as internet giants like the Google-owned video site, Facebook and Google itself are being pressured to act regarding illegal and extremist content making its way onto their respective platforms. By only banning videos specific to the mass shooting, it indicates that the video-sharing service will take action toward curbing risky content - in the aftermath of a deadly event related to said content.
YouTube isn't the only entity to change their stance on bump stocks. A statement that the company has been sending to reporters reads, "We have long had a policy against harmful and risky content".
Fully legal under current USA law, bump stocks are an cheap way to allow a semi-automatic rifle to operate similarly to a fully automatic weapon that would be hard for regular citizens to obtain.
Semi-automatic weapons are legal to purchase in the US.
