In the round 702 that happened a few days ago, somehow all submissions were rejudged on all tests, which include some of the uphacks that were done after the contest's hacking phase. For example, my F retroactively changed from accepted to TLE. Maybe this has changed, but I thought the original point of uphacks were to strengthen system tests for practice, not to change the verdicts after contests finish.
I'm a bit sad about losing first place, but it was unofficial for me anyway, so that's not really the point... but, is this a permanent change in the stance on uphacking? I was only hacked because I talked with someone else (after the hacking phase, when it was supposedly final) about a case I found that would cause TLE. Will it be better to keep this sort of thing secret in the future?
