Firstly, the Sagittarius. From some simple google work, Sagittarius symbolises: Freedom, optimism, fairness, intelligence and most important HONESTY. Keep this in mind a moment.
Delock, in Scrabble means nothing. Not a real word. However, in Urban Dictionary terms, it's a combo of Delete and Block. This, to me, especially since there are Lock AND Delock, suggest a SECURE-YO-BETTER-WATCH-YO-AZZ unlocking method, as well as inherent FEAR OF CAPTURE by government agencies or authorities.
Next, the first suggestion was that it was similar to WebdriverTorso. Now, try and stay with me...
What if, the OP of UFSC is trying to BREAK the YouTube security system, and that is why it was all removed from YouTube. Keep in mind, we have been living in a cold war since WWII?? Currently China has an embassy in ALL 8 AUSTRALIAN STATES for what I can only assume is for a quick GTFO of Dodge...
What if Delock in cooperation with Lock is supposed to operate in a way similar to Steve Jobs and Steve Wozniaks AT&T free dialler hack? By this, I mean bypassing Bitcoin mining for those Uber Valuable solutions to the algorithms mined, as they are at your fingertips. Maybe the combination IN SOME KIND OF BLOCKCHAIN, of the individual images (I know, that's a bucket load of mathematical combinations) in conjunction with another setup of Audio and Video could open the Almighty Eye, and allow the individual to spy on the Powerful? That COULD potentially explain: 1. Why YouTube booted it so quick. 2. Why the OP doesn't want to be found, they need everyone to realise what they have discovered about a corrupt system and how to exploit its flaws? And I don't mean hacking YouTube necessarily, but what if.... it were an advanced method of Blocking your whereabouts from peering government eyes, whilst still unlocking the keys to the castle?
Which castle? The one which holds the Unfavourable Semicircular Table for the heads of the Illuminati?
Can you imagine seeing their faces? Wouldn't you like to know who holds the reins attached to your bit and blinkers?
This could be way bigger than people think.
But it's just another theory. Call it what you want.
But I am an artist. Musical mostly, and I don't feel that what I heard was even "outsider music or art". I believe that for so many files of such creepy and weird description, being autoloaded each 2 minutes by an unmanned machine running a script to avoid detection, maybe sourcing the files which had been securely presaved to a cloud store for self preservation and security, it's all too mechanical.
Even mechanical music is generally more free-form, thus my theory is that ALL OF THE FILES are required to unlock and break the system security that allows THEM to spy on us (think back to waiving your rights, 9/11) and we can now spy ON THEM.
Ok, some sounds logical, some crazy. But just consider the concept before you troll or mock me ok. I just want to help.
