No one has any questions, so I guess I will start the marathon again (3 weeks later)

Solve this Baconian cipher where A = 0 and B = 1:
ABAAAAAAAAABABBABBAAABBABBAABAAAAAAAABABBAAAAAAAAA
ABAAAAAABBABBABAABABAAAAAABBAAAAAAABAAAAABABBBABBA
ABBABAABABABABAABAAAABBABABBAABAAABABABAAABAAAAABB
AAAABBABBAAAAAABAAABAABBBAABAAAABAAABBBAABAAAAAAAA
ABABBAAAAAAABABBAAAAAAAAAABAAAAAABBABBABAABABAAAAA
ABBAAAAAAABAAAAABABBBABBAABBABAABABBAAABAABBBAABAA
AABAAABBBAABABAAABAAAAABBAAAABBABBAAAAAAABABAABAAA

"Everything is just a meme! Don't tell me you don't know! Because of course you do! It's because of you that I'm disanythingitized! So do you like your prize? Was it worth all the views?"

This one took me a while, mainly because I was stuck on "disanythingitized" but learning a new word never hurts!
Here take a morbit cipher:
9 3 2 7 4 7 9 7 2 9 8 9 3 9 6 2 8 2 7 8 7 1 4 3 9 6
6 1 5 9 5 3 4 7 9 1 3 2 8 9 5 9 7 6 1 8 5 2 5 1 5
3 4 7 9 7 7 2 7 6 9 8 1 5 9 6 9 6 8 7 1 4 3 4 6 2 6
2 8 2 6 6

OO,OX,X-,XO,XX matches to 9,6,8,5,3. (respectivly)

That was fun.. Here's my answer:
Solved plaintext: "I would say my sense of adventure outweighs my grace"
Here's an affine cipher from scioly.org/tests:

Ciphertext: Dgdqfrad ynsbh nerpy ycd xdnycdq, epy ar rad mrdh nafyctal nerpy ty.

Key: a=17, b=13
2022 States Div B: Anatomy & Physiology 2nd, Codebusters 8th
2022 Nationals Div B: Anatomy & Physiology 9th :), Codebusters 37 :|
2023 States Div B: Anatomy & Physiology 2nd, Crave the Wave 2nd, Dynamic Planet 1st, Codebusters 6th
2023 Nationals Div B: TBD...

My answer:
Plaintext: "Everyone talks about the weather, but no one does anything about it. "

I must admit this is one of the better plaintexts for a codebusters question that I've ever seen.
It seems evil to put an aristocrat here, but this is just one of my favorite quotes. (Normal Aristocrat)

"This life is like a swimming pool. You dive into the water, but you can't see how deep it is."
I despise Aristocrat with a burning passion, so I'll change the topic.
"Xez okz'h kwcahrozu wza gwzkodank yraz jmfmzgozu hra ezobanka...jeh hrok...dwak teh m kcofa wz cs xmga."
An affine cipher with A being a prime number greater than 20, and B being a multiple of 6 less than 15.

 ¨Fun isn't something one considers when balancing the universe... but this... does put a smile on my face¨ 
That affine was pretty fun! Here is another affine:

B = atomic number for the chemical Chromium
A = smallest double-digit prime number

"In real life, I assure you, there is no such thing as algebra" 
I had a bit of trouble with the modular inverse, but I got it eventually.
Here's a Baconian where A=0 and B=1
