Ist youtube.com sicher?

I say youtube is the best video service but I decided to give a few certain ratings the way I did for these various reasons; Child Safety; Youtube does not realize how perverts are using it; Take for example all videos that have young children displayed [I learned of this example actually from a facebook joke page] All videos that display any young girls doing gymnastics and such viewer demographic is about 100% males of the age 35-82 {So don't count on google to ensure that your child may not end up in pervo servers, any security professional would know what I'm speaking of} So my child safety rating was an absolute 0 Privacy; With the new revelations of PRISM and other such activities, it's hard to really determine if google is that trustworthy at this point, and youtube is a google ran company, but I also understand that the NSA is a very professional group and they do not attack people for well; anything a regular civilian would deem as absolutely obsurde and stupid. Knowing as well though how non-e-terrorist anon members seem to have no issue [People fighting pedos, north koreas threats, any threats essentially to international security the same way any military or police groups doing but on police level and clear human rights violations, nothing that could concern national security in the reality of things]; which is a good thing, googles shown their trustable in this matter, the paranoid members of security need to relax on some things to anyways and it shows they don't bother your true privacy. Vender reliability; Well with the new form of youtube buffering, the reliability has become annoying on all degrees of facts that videos streaming are now pausing every 5-10 seconds [How annoying is this seriously?] Though they have the greatest video server in the world, this new buffering feature has annoyed me into not wanting to stream any longer from youtube but rather download the videos VIA HDDownloader so their high quality and I can watch them and not get headaches. Trustworthiness; I'd say 50-50 but 100% if you're someone not bothering to be doing anything they really shouldn't be. {Provided by a security professionals true opinion :)
