Good point. I should have looked there myself

I notice from luigi and fluffy's post that there was code run to check whether the exploit was used on the Monero blockchain, and this found it had not been exploited in Monero. Out of curiosity, do you know if this code has been used to check other blockchain's?
I doubt it (but I don't know with certainty). The chains that implemented a fix similar to Monero would check all previous blocks when resyncing. So any successful resync would mean that there were no actual exploits.
