Exactly my point.
Well... again, I may not know the details of the legislation and what the FCC plans to do, I work in IT and can speak (with expertise) to what they can do realistically to check video content. Estimates of video uploads to YouTube on a daily basis are in the 1 petabyte range. One petabyte is 1000 terabytes. This is daily.
Scanning accounts to determine what their content settings are, can be done in relatively short order. So can scanning existing content that has already been flagged as inappropriate. Scanning all the video content on YouTube, considering in the past year alone there has been an estimated 365 petabytes of data uploaded, would take several lifetimes. And if they could somehow scan all the video content from when YouTube began until now, there will be another petabyte of new content by tomorrow.
I work in tech too, and while you're right about the volume of content, since the FTC is the judge, jury, and executioner in the is case, the process doesn't have to be fair or transparent. If you're int the wrong with them you're wrong and the appeals process, if it exists, is probably costly. What I'm saying is that if they were to scan the content correctly, it is a huge task, but they can just half-ass it and be done with it and start handing out fines. They just have to fine enough people that that others get scared.
