I'm uncertain about being an organizer next year. But if i do, I'll ensure to engage with the teams involved prior to making any public announcements.

However, unlike that case, what I was overlooked in this case is that it may not be "obvious cheating". It is certain that to be disqualified by the rules, but there may be a "victim" to it.

2 years ago, a similar anti-cheating mechanism was applied in a domestic CTF. (of course, unlike codegate, there were many challenges for beginners and there were limit of team size (<=4)), and a total of 22 teams were caught cheating on 6 challenges. (obvious cheating).
