I got a TLE during the contest, but my resubmission passed without changing any line of codes several secs later.
It seems that system failure happened, and I got 5mins penalty, and it' not the first time this case happend, so do you have any formal way to ask for rejudge.

My suggestion is that leetcode can add extra rejudge button next to the report cheating to fix this case.
You can add some filter to detect abnormal judge status to avoid abusing of this feature.
