## Tears
We - after brainstorming hundreds of different ways to understand the text - understood that we should use Tor. (Onions make us cry).
One teammate posted a wiki/index containing .onion URLs and a description of the site.
http://dirnxxdraygbifgc.onion/
From that site we found the forum by trying to find something like `galaxy` or `universe` that was mentioned in task description:
http://galaxy3bhpzxecbywoa2j4tg43muepnhfalars4cce3fcx46qlc6t3id.onion/
And then this one by looking for the obvious username from the task description `un1v3rsek1ng`:
http://galaxy3bhpzxecbywoa2j4tg43muepnhfalars4cce3fcx46qlc6t3id.onion/profile/un1v3rsek1ng
Found loads of fake pictures because someone sabotaged us :'(, but eventually found the right picture.
Then figured the pieces of text on the picture was base85, put the pieces together, decoded it and got the flag.
