Yahoo Answers was closed down on May 4th 2021.
Yahoo decided to close down the Yahoo Answers website because it was becoming overrun by trolls and the answers quality and engagement were declining.
They decided that Yahoo Answers was not worth keeping as it was not profitable for them anymore.
I used to visit Yahoo answers but stopped going their too much around 2017 and preferred to go to Quora, Reddit or even this website.
I do have to agree with Yahoo though that Yahoo Answers was declining and I too would've probably shut it down or at least left it as a read only site.
