Also, do not surrender your boarding pass! (If you check in online, make sure to also send an email copy to yourself, and/or to print out more than one copy to carry with you. If you obtain it at the airport, go back [to another agent/customer support desk/self-service kiosk/whatever] and ask for a reprint, stating that you have misplaced/lost your boarding card if necessary).

Then, include all this evidence with your filing. As the airline digs itself deeper into a hole, it will incur further penalties for falsifying the record as well as the IDB/voiding. This also makes it clear that it acts with mala fides against customers with confirmed reservations and makes it more likely to be subjected to future enforcement for the issue.

Truly, I cannot understand how this self-destructive behavior could seem logical to airline staff. At the time someone is flying on an F-ticket, with BP's in hand, the game is done.

And I agree with you and deltahater, when LX does this again, let's all buy tens of tickets. They'll all be enforced. We know it and so do they.

Then we can leave plastic Travelocity gnomes as souvenirs in the F lounge at ZRH and onboard, and send one to the CEO and General Counsel.
