But I am eager also to give information from outside activities. Of course I will never know all sites or afford to buy memberships to view their content. I know plenty and have seen many, but I cannot pass it on because of respecting copyrights. There are no problems giving links or to post sample material as published already for promotion, except the copyright owner would contradict. When compiling clips or capturing stills from external material I always tried to ask for permission, but many webmasters, especially those of larger and well established sites unfortunately don't ever answer. A praiseworthy exception I have experienced at kink.com. Although they own a wide spread network and run several premium sites with plenty of different content, they kindly granted permission to post some of their material on this site.
