When the organizers finds out that you have violated the rules, you may be disqualified, even if the game result has been confirmed.
With players who keep winning and who keep rising in strength, there may in some cases be players who are disqualified on the grounds that their exact rank cannot be judged.
Also, players may be disqualified when there is an obvious disparity between their registered rank and their real strength.
If it is confirmed that you are using Go software, you will be disqualified from this tournmanent and forbidden to participate in all other tournaments.
Emphasis mine.
They don't say how they might confirm the use of Go software, especially since you normally play from home.
The disqualification based upon disparity between registered rank and real strength might be used in cases such as Metta's where he was apparently playing above himself, but the use of go software was not proved.
