At the start of 2025 there were several questions paraphrasing a contest question (2/3/36 of https://files.usamts.org/Problems_36_3.pdf) including
- https://math.stackexchange.com/questions/5014709/the-hour-and-minute-hands-of-a-clock-have-been-moved-to-uniformly-chosen-random and
- https://math.stackexchange.com/questions/5018262/a-quirky-clock-vs-a-normal-clock and
- https://math.stackexchange.com/questions/5020133/frozen-clock-experiment
When the last of these appeared, I could not find the previous versions as they had been deleted and so I could not find when the contest was due to close and whether the latest version should be treated the same way. Fortunately in this particular case another user could.
Is there any way of tracking these sorts of questions and the information they contain?
