**Solution**
The hint is for [this video](https://www.youtube.com/watch?v=F5bAa6gFvLs).
After `nc sneakers.wpictf.xyz 31337`, we are greeted with a big block of 1's and 0's:

Given the video which features a blind hacker using a Braille "monitor", it was quite clear these 1's and 0's represented Braille characters.
After some automated deciphering:
Welcome to the brai
lle terminal! I'll
only give you the fl
ag if you can prove
that you are visuall
y impaired. Please
type 'continue' in b
raille to begin. Ho
w to write a respons
e- Write each row o
f braille as 0's an
d 1's, then place a
n 'x' at the end of
the row. This means
that all three rows
are written on a si
ngle line of input,
in the form ...x...x
The individual parts of the challenge asked to:
- type `continue`
- solve a simple mathematical problem and give the numerical solution
- type `ACCESS FLAG!`
- type `please`
The final `please` was a response to the server saying "Ah ah ah, you didn't say the magic word!", and referencing [this video](https://www.youtube.com/watch?v=RfiQYRn7fBg).
