Are adult video streaming sites legal? Sites that host the videos vs sites that embed from other sites. Are either legal?
Yes, sure they are legal. If you own the right to stream or embed the material then it doesn't matter if it is cartoons or porn. The key is the right to show the material, not the content of the material.
Conceptually, they're legal. So long as they have the rights to embed them (most adult websites DO allow embedding as it's promotional traffic...traffic + sex == $$$). On a site to site basis, the site streaming the content from another provider may be violating certain hosting agreements if they're in a certain datacenter or shared hosting plan which prohibits such content as part of their acceptable use/terms of service agreement.
I see sites that stream videos. I know they don't own the videos. Just wondering how they get away without getting in trouble. Also I see scripts that grab videos from those sites to add as a database. Wasn't sure if it was legal or not since the scripts would grab from other sites.
Maybe if your motive is clean. As far as I know, the moderator will delete the video if they found out that you violated the streaming rules.
