This is my thoughts on this situation.
Anyone who thinks the problem with Tubes can be solved by a program is a dreamer. It won't work and this is why. If anyone knows otherwise I will stand corrected.
Large traffic tubes sites exist because they can publish full length scenes and reap hundred of thousands to millions of viewers a day. Without the full length videos the traffic will migrate, to the other Tube sites with full length videos. It took Pornhub and a few other Tubes 2-3 years to go from practically nowhere to be the top porn traffic sites.
In that time they have educated the customer he doesn't have to pay for porn, in fact Tubes offer a better deal than most porn sites. So if the top 20 Tubes take up this scheme
with a vast majority of the porn producers/owners AND
delete all the full length UGC videos and their profiles. The surfers will soon realise and go to the 21 to 40 top Tube sites of today. Which will become the top 20 in a very short space of time. Because the surfer is now educated and will go looking.
So Top Bucks, FSC and all the others who jumped on this band wagon can you see how it will not work? If you hamstring 20 Tubes with a program another 20 will take their place. Same goes if you do it to 2,000 tubes. And those that replace them will see the folly of signing up to this and will be in countries you can't chase them so easily.
I bet Manwin have realised this as well so have no intention of making it work.
And if Top Bucks have such marvelous content that the viewer has to have, as no other content will take it's place. I'm going to be surprised.
Edit And another thought. If Manwin or any other top tube comply with this scheme and see another tube coming up to their level, they can't keep buying them out. Because once they get the new tube to comply, the next one in line gets their traffic and becomes a threat. They can't keep buying tubes because their traffic is migrating. Then change the new one to the reason the traffic is migrating. Running around chasing their tails.
