• I guess most solver put the string through a ROT decoder to check through the result. You will find that some parts of the text will become readable at different rotation amount.

• On closer look, we notice that the rotation amount starts at 1, and it increases by the amount in bracket [ ] where the alphabet is converted to 01-26 for the next section. [#] resets the rotation amount back to 1. The message decodes to:

  ALRIGHT WELL SEEING AS HOW MY IDEA OF A FUN LITTLE PUZZLE IS TOO EASY HOWS THIS GIVE ME YOUR HONEST OPINON I DONT KNOW HOW BAD IT IS CAUSE I WAS GOING MAKE IT ALOT EASIER YEAH SORRY THOSE LAST FEW LINES WERE THROWAWAY TO INCREASE THE SIZE AND THUS COMPLEXITY OF THIS SIGH I MEAN ITS KINDA SAD BUT NOW ITS FIVE LINES AND BIG ENOUGH TO THROW PEOPLE OFF THE SCENT AND THIS IS THE ONLY LINE THAT MATTERS DONT YOU HATE ME HERE TAKE IT EHEGT NOW I CAN GET A THOUSAND BLACKLISTS FOR BEING EVIL

• The giveaway code is EHEGT, and applying the Part 2, we get the solution: EhEGt
