Competition Rules

🙅‍♂️ Don't delete flags or break services. While organizers try to maintain challenge resilience, mistakes will be made. Instead of abusing them, report them to the orgas for kudos.

🙅‍♂️ Don't share flags or ask for flags. It's a competition, do your personal best.

🙅‍♂️ Don't generate excessive load. Bruteforcing or DirBusting the scoreboard will not be necessary, let's keep it down.

🙅‍♂️ Don't troll, spam, flood in the chats.

🙅‍♂️ Don't register multiple accounts.
