11th factory day: Community Puzzle for Clair Obscure. Ended. Solution added

Hi again. My account will be 11 in about 10 days. That's why I decided to make another puzzle train. 11 GAs for 11 years, I think it's fair enough. GAs are mostly some gabage but that's not my problem.

If some of the puzzles look familiar it's because I stole them.

I'm still too lazy to make proper hints myself, so please, share any hints with each others, just don't give direct answers or links.
Just to be clear: you can and probably should give each other any hints/clues/ways for a solution other than direct answers.

1. Open the imgur link and get the code in the description.
2. 5 letter codes are used on SG not only in GA but also in discussions.
3. Imgur links have 7 letters.
4. SG comments too, just check permalinks on any of them.
5. Nonograms have unicode codes too. Check RosimInc's Café thread.
6. Just Steam subs. You can find them on SteamDB if they are locked for you for some reasons. 1st letters give you the code
7. The Bacon cipher.
8. Old phone keyboard layout.
9. UN/LOCODE city codes. You can search them with "XXXXX city" or something. 1st letters or names give you the code.
10. Ctrl+F and letters "a", "b", "c", "d" or "e".
11. The simple alphabetical substitution cipher. You can either solve it by yourself (it's not that hard), or try to find autosolvers. Like this one
