There's a couple of questions on Hackernews that repeat a lot. I'd say human nature, not bots. Some questions have a slight twist or personal background, sometimes a year is added in hope to get recent answers. Same on AskReddit. It's up to the platform (or moderators) to enforce anything.

"Ask HN: How to find mentors?" "Ask HN: How to find a mentor/advisor?" "Ask HN: Where to find a mentor in my city (or any)?" "Ask HN: How to find a mentor?" "Ask HN: How Can I Find a Mentor?" "Ask HN: Where do you find mentors online?" "Ask HN: Where can one find a mentor?" "Ask HN: How do you find a mentor at a new job or a new place?" "Ask HN: Best way to find a mentor" "Ask HN: How did you find your mentor?"...

or which books people can recommend, how to people writes notes, how does your company do knowledge management, how do I learn web development, how does a backend developer switch to frontend...

The other day I was about to answer a question about the city of Krakow (where I live). Then I opened the list of hidden answers and saw a guy warning others not to waste their time, since the OP has asked the same question about every other Polish city. Sure enough, a search revealed exactly that. The question actually employed the name "Kraków", which is the Polish spelling.
