Rules

No sharing of flags or solutions. The entire point of a CTF is to learn, so simply handing someone a solution won't benefit them.
No attacking the scoreboard.
No brute forcing. All challenges can be done without DDoSing or bruteforcing flags. If there is any need to run a binary a million times, it will work on your own system.
No DoSing. If you intentionally hold the challenges of the platform down, you will be banned.
