The Videos that get removed are usually uploaded to Third Party Servers such as mab.to or zippyshare.com or other sites that let video content be uploaded.
Reallifecam (RLC) has a policy about their Intellectual Property been posted and they get a DMCA Order to get the Content removed from the Third Party Servers that it was uploaded to.
When the Video Link becomes dead and the Video is no longer present on the servers it was uploaded to, those Links get marked as Video No Longer Accessible....
The only way to get around it is to get a Premium Membership and Upload it directly through the Forums Servers. I have been here 3 years and I can verify the fact that any content uploaded on the Forums Servers are still intact and available to download and view. The only time a file is removed from the server is if the uploader makes a Valid Request to have it removed.
A Premium Membership to Cam Caps is only $12 Per Year which works out to $1 a Month.
With that you get access to
Video Gallery
Image Gallery
Members Only Boards
Can view ALL Attachments
Disabled Ads
Currently there are over 17,000 Pictures (Images) & Over 1,800 Videos in the Attachments Center and there is Multiple Content as well in the Gallery. It gets larger everyday as Content is always added to it on a Daily Basis.
The Advantage is with a Premium Membership you get see all those Pictures and Videos. Without a Membership you can only basically view what content gets posted from Third Party Servers for a limited time until they are ordered removed.
