Hello earthlings, I have made a little Capture The Flag contest (CTF).

You will find the correct answer in the following format: Flag:[answer].

Rules:
- Everybody can join, even mods!
- When you find the answer, pm it to me with your BTC address.
- I will give out some hints along the way


Prize:
- 50 Dollar in BTC (calculated on the moment I receive the correct answer)

Starting point:
https://pastebin.com/RetXK6sC or if that's still private then: https://anonfiles.com/55uaHcW6ua/pastebin_txt_txt

First to send the correct message wins.
Good luck!

Btw you say you cannot send me a message, but you already did? And there you state that you "think" you have
it, which I am pretty sure you don't seeing that you will know when you find it.... so it's still open people!
