Ultimate Tabletop Giveaway Contest/Newspeak Puzzles

I don't usually post things like this, I don't usually enter them because I don't win em', but I checked out this one, and I stayed for the Newspeak Challenge puzzles.
So there is this Ultimate Tabletop Giveaway Contest put on by Inside the Box Board Games. There are tons of prizes and lots of ways to get entries.

Cool, right? But then I noticed you can get a lot of entries by doing these Newspeak Code Challenges. (Basically the publisher is coming out with this new legacy code cracking board game later in the year called Newspeak on Kickstarter, so they're creating buzz by making these mind numbing teasers). Doing the challenges gets you tons of points, so I thought yeah, sure. I have some time to kill and I'm pretty good at puzzles.

No.

These puzzles are mean. Verging on rude.
You have to do what to get the answer?

There are 3 puzzles:
Newspeak Code Challenge 451
Newspeak Code Challenge 1984
Newspeak Code Challenge 160811

The number of the challenge doesn't have anything to do with the challenge itself. All you need is cunning and Google. It took me probably half an hour to figure out the first one. Probably 2 hours to get through the second one (I'm not fast, but I got the job done, ok?). And I've been going at the third one for a day and a half with no answer. A DAY ... AND A HALF! I don't even care about the contest anymore, I just can't let this puzzle lie uncompleted. I need to know how it works!

So come, join the contest. I need your guys help getting the third puzzle. I just can't brain anymore.

Do they have to be done in order?

Nope, not at all. They aren't related to each other.

I'll give clues for the first two puzzles if you guys get stuck or get to the point where you want to chuck your computer. 

Yes please for tips on the first one. I've been severely struggling on the first puzzle, been at it for about a day, which means I've probably overthought it bit can't unthink the wrong ideas!!

The passcode is 8 characters long. Half of it is within the text near the bottom of the page (you may have guessed this), and the other half is within an element in the page(aka, not in the text). If something looks off, it's probably on purpose.

Yeh I got all that but don't know how far to look. Been learning the Marathi alphabet, bee colony algorithms and history of the Levantine free states lol. 😱

Scroll to the bottom of the page and without looking at any text, stare at the page. 
It might take a minute.

Haha that's ridiculous, Jesus, I suppose it's as good a procrastination as any...

The next one is more straightforward of a word puzzle. Just keep in mind that these puzzles are meant to be able to be figured out by the mass public. No special skills required.
