I don't mean to be mean or spoil the fun or anything but I feel like a lot of internet mysteries could have been solved with a little bit of common sense/a proper application of occam's razor.
> Was worldcorp a pedo ring
It was probably just an honest mistake, that would be a pretty stupid way to run a pedo ring but it would be pretty easy to accidentally mistake evil shit that made its way onto the normie net for a generic spooky video and add it to your arg.
> Was the original sad satan (video) creator doing a pizzagate
Probably not. What most likely happened was some dude wanted to create a viral hoax and made the original videos and fake onion link and some loser on 4chan gamejacked his "mysterious darkweb poster" character and used it to show people cp. Also, and I have to moralize for a second, why the fuck would you ruin a man's life over the fakest allegations ever? There is no proof that the anonymous person on 4chan and the uploader of the video are the same person. But what really gets me is that these mystery youtubers will just offhandedly mention that someone was harassed and doxed until they left the internet over the least real allegations ever like it's part of the internet mystery. No, that was bad and you should acknowledge it.
> Is there an original version of sad satan
Probably not. All the alternatives presented are less likely than the idea that the dude just made it up for a creepypasta.

Not to be disrespectful to the people who lost their computers but you shouldn't download things from an anonymous website filled with trolls.
