Following the removal of several threads from one Forum which mainly consisted of lengthy pirated video clips, the JUB policy has been clarified and the new point # 23 is detailed below:

Policy Regarding Video Clip Posting:
JustUsBoys encourages its users to share and discuss like-minded interests, but we also appreciate the creative works of those in our industry, and we will not be a party to infringing on their intellectual property rights. Only one single link is allowed per username per thread to downloadable video files. While freely available 'teaser' style clips and Rockettube/XTube type links are generally OK, lengthy video clips are not. If the video file is from a commercial production, then no other links can occur in the same thread from the same video production. Additionally, threads can not cross-link to other threads sharing videos from the same production.

Please ensure you are familiar with the expanded Code of Conduct: http://www.justusboys.com/terms/coc.html
This has been updated and should be re-read in it's entirety.

Those people with Blog or Website links in their signature should also be aware of this:
