The 3rd stage of the annual John Van Caneghem Tournament (2007).

...However, a similar situation with unverified players should be prohibited, especially if cheaters start to appear, given the cloning of saves with minor changes by ONE player in order to earn double or triple the amount of money from a single Tournament for their result.

Do you think a player would send 3 saves from themselves? Wouldn't it be safer to use 3 different email addresses? And there wouldn't be any suspicion.
And it would be even better if cheaters could not transfer them to another player. Then there would be no point in these "manipulations."

...The rules prohibit discussing Walkthroughs on the forum. However, no one can prevent players from doing this in PRIVATE MESSAGES...

Point 12 of the rules:
Discussing the Tournament during its course is PROHIBITED!!!
That is, both on the forum and in private messages, and anywhere else. It is impossible to track this, but when they themselves say that they discussed the Walkthrough... (they should have kept quiet :))

People, people, people! Hello! Please note - Rapper is my brother, we live in the same apartment! ;) We ALWAYS KNOW EACH OTHER'S RESULTS! There's nothing you can do about it!

How does that work? Why do you know each other's results? Each of you has your own Walkthrough, and no one interferes with the other's. Maybe someone "accidentally" looked at the other's Walkthrough? (although the rules do not prohibit viewing another's save)
Or did you violate the rules and discuss the Tournament?
