True, but I still don’t expect it will be a big problem. If there are a lot of submissions, the effect will be small, and if it is paying enough attention to your source code for it to be possible to trick it into not halting, then it is probably looking for a way to achieve mutual cooperation, so tricking it is still not a good strategy.
If you trust all sufficiently smart players to try to induce (Defect, non-halt) if (Defect, Defect) is otherwise inevitable, the effect adds up over a hopefully significant portion of the submissions.
