The problem with these sites is that the scenes being uploaded are, for the most part, being done so without the permission of the people who own the copyrights on them.
This means that tons of people get to watch the porn made by pornographers, without the pornographers ever seeing a penny from it. Not from purchase, or from advertising, or from anywhere else. Clearly, this is a problem.
We here at adultdvdtalk, a forum which has many members who are in the porn industry themselves, have decided then that we will not support these tube sites in any way. We will not link to them, or say their names, etc. As such, I'm going to have to close your thread and deny your request for more info about these sites.
There are, however, some threads discussing tube sites and their impact on the industry, so if you'd like to know more feel free to search ADT (using the search function in the top right corner of the page) for threads that have "tube site" in the title. (Be sure to change the search date to "in the last 2 years" or something like that, instead of "last 30 days".)
