Most sponsors that provide affiliates with video clips typically dont mind if they get used on the affiliates own tube site, at least that has been my experience.

Yes, i would most definitely stop other webmasters from posting sponsors content, YOU want to make money from that sponsor content, not people posting clips to your site.

On the subject of whether tube sites are worth it, i just recently launched Tube Tender in to beta testing and initially, the figures im seeing in terms of sales to traffic arent spectacular but, they arent bad either, you have to remember, 99.99% of surfers hitting porn tube sites are looking for free content, any dollar you can squeeze out of these surfers is great because it turns them away from 'free porn' users to 'paid porn' users.

Right now our median conversion ratio on http://www.gaytubeaccess.com is 1:600, which as i said, isnt spectacular, but it isnt bad either considering the surfer is used to finding porn for free on 'tube' related sites.

I am also sure that once we go beta with our niche specific tubes, this number will be considerably lower.

As for hosting of your sites, National Net comes highly recommened by myself and several others on the GWW Community you may want to check them out

Got your ICQ request also and accepted it
