GoFuckYourself.com - Adult Webmaster Forum - How deep are the global porn reserves?

Looks like some tube sites are posting up to 100 new stolen videos/day now to keep their visitors happy, which made me wonder:

1. How many of the porn videos have been produced so far in the world? 10 mil, 100mil...?
2. What % of it could be easily stolen? I mean videos from dead studios, weak studios, stupid studios that to not enforce their intellectual proprety for whatever reason etc, how many of those are out there that could be used as the source of easy updates for illegal tube sites?
3. What is the period of time that those global reserves of "stealable" porn will be able to sustain the current updates rate for illegale tubes?
4. What will happen when illegal tubes will simply run out of the videos to steal?

I few more thoughts/estimations to through into the equation:

- Not all tube site update with 100 videos/day, but there are hundreds of such sites (I mean hunderds with considerable traffic), and they rarely post the same stuff. In a very rough estimation, I'd say that illegal tubes "industry" consumes about 2-3K of the stolen videos every day.

- Production of the new videos is down at least 50% and most likely cannot keep up with their burning rate, and not all of the newly produced videos could be easily stolen. Actually, I believe that the % of videos that could not be easily stolen increases in the new production, as the weaker programs/studios or those who simply do not care to enforce thier intellectual property close every day and only the strongest ones remain that do actively enforce their copyright, leaving illegal tubes even more dependant on the remaining pool of porn that has been collectively produced by the human race so far.

- I believe that trend is that none (or very small %) of the newly produced videos will be available for an easy steal within a 1-2 years from now - both because of the active copyright enforcement and content protection features such as encrypted streaming.
