SOLUTION

1. Finding the code: You needed to view the source of the webpage (Ctrl+U) and look for the hidden link leading to a imgur image! The first imgur was this one but a lot of people had troubles so I made this other one.
2. Once you found the image you had to remove its extension ".PNG" or ".JPG" to be able to check the imgur description and start cracking the code.
3. The only thing you had to do to use correctly the code was to... INPUT IT BACKWARDS! That's it, Q Z F Z Z O 9 E became E9OZZFZQ, those 8 characters naturally were the code to a ItsTooHard.com puzzle. I added an extra hint in my Steam Profile, I said it was 2 clicks away (my avatar + steam profile icon).
4. Solution of ITH puzzle.

THAT'S IT! There wasn't any other bizarre stuff to do, some didn't even find the imgur hidden link, some got to the image but didn't check for the description, and BOTH of those things are explained in Zelgh'd puzzle guide, so those people were too lazy to look. Then I added a ton of hints to the ITH since people were having too much troubles. I had issues with 2 GAs so I did the 3 extra wagons train and posted its link on all of the other GAs.

In the end there were 79 players, 26 solvers (33% success rate), 2311 guesses (average of 2.66 guesses per Q) and 11 GAs!
