Description: What a weird username this starnerd starknight has. I wonder what hobbies they’re into. Maybe they have an account not mentioned on social media. Find the flag on their account’s profile page. Flag format: jellyCTF{flag_on_profile_page} Note: The results of previous challenges are not relevant for this challenges (though clues from those sites may help)
Remember how I was talking about why I did not check the “taken” accounts first from https://instantusername.com/ in my stalknight_3 writeup?
Well, instantusername.com query to all the different API’s are actually broken!
How did I find this out? I manually went through each website that says it was “available” and manually checked if it was actually available. Sure enough, one of the websites had the flag!

What did instantusername.com say?
Moral of the story: don’t trust automated tools to a great extent!
