Youtube has announced stricter rules for gun-themed videos.
The site will be banning instructional videos on how to assemble guns. It will also ban videos that promote or link to websites that sell firearms.
The new rules are set to go into effect next month, although some gun bloggers say they've already been affected. Gun seller Spike's Tactical says its channel was suspended and will be switching to Facebook and Instagram.
Another gun-related channel, InRange TV, says it will be uploading its videos to PornHub instead, calling the porn site a "proactive voice in the online community".
A Youtube spokesman says the site has long prohibited the sale of firearms, and that they routinely update their guidelines and policies. The website has been getting much stricter over content and monetization over the past year.
