Rules

  1. Don't be a dick. Be considerate to others. While this is a competition, sportsmanship is important. This doesn't only concern people from other teams, but your teammates too.
  2. Do not attack the infrastructure. This includes but is not limited to (D)DoSing, use of automated scanners, trying to modify the scoreboard, taking other challenges down and brute-forcing flags. Challenges have clearly defined scopes, please follow them. If you are unsure about something, ask.
  3. Do not share flags or any advantageous info between teams. Not for money, not for any other compensation, not for free. This is a competition after all.
  4. Don't horde flags. It may be cool and funny to rise to the top in a millisecond, it isn't as cool and funny for everyone else.
Failing to follow any of these rules may result in a disqualification and a ban.
