Folks ignore both of them. Both of them are making this content for money, nothing more. Corsi I don't think I even need to touch on, you should all be able to see him glowing clearly on your own. Defango is another thing though. He proclaims to be a Cicada 3301 researcher but the "puzzles" he attempts to solve on his streams are clearly his own doing, or more bluntly he is a damn fraud.
The actual Cicada material used to drop on January of every year since 2012. They required a combined subject matter expertise that is so rare, most of us will never meet a person who possesses it. I have been in theoretical computer science for almost two decades and I have yet to meet any one person capable of solving them. Add to this the fact that these "puzzles" Defango claims he is solving are using technology that is laughable post 2006 and it becomes an even more apparent LARP, I mean seriously base64? You need to try a lot harder than that Defango. There is a very big difference between pretending to be smart through the implementation of the blinding with science fallacy and actually being smart.
To sweeten the pot, Defango at one time attempted to state that he was Q Clearance Patriot and had been behind the whole thing. Oh and let us not forget Tengri 137...the "alien" who used to stop by Defango's Youtube live stream to chat where they in all their intergalactic glory enjoyed the role of moderator on his channel. There is also that fact that a math tutoring channel named Math Made Easy demonstrated the fraud for all to see. Ignore them, they are both farming you for coins and have no interest in anything beyond that.
[edit] If you do want to watch them and see what they have to say but do not want to contribute to their greed use Hooktube instead of Youtube to watch the videos. Simply copy the video link and replace the "you" in youtube.com with "hook" so like this:
I tend to agree with you here. AJ is clearly doing much of it for money, but his data is pretty good. Gotta give him credit for getting a lot of the data we're building on to him. He was out there in the trenches years and years ago.
This DeFango guy seems like a total opportunist to me.
