This site is inherently a bit opinion-based. That's because there rarely is a definite answer to a question here. If there were it would quite often be better to ask on one of the other sites of the network that are about real-life stuff. We are creating new worlds and elements of worlds.
The problem is: from time to time something is so opinion-based that it should be closed immediately, but it's funny enough that it slips right through the normal screening process of the site.
Then it hits the Hot Network Questions (HNQs). Suddenly everyone on the network can see the question, which often has a click-bait title.
Then everyone rushes over from other sites to take a look at this weird question that suddenly popped up on the right side of their normal everyday often work related questions and they want to have a quick diversion.
They see the funny question and upvote it. Because there are a lot of people on the network such a question gets a lot of upvotes.
Often the question gets closed later, because some regulars bring the topic up in the chat or on Meta. Until then thousands of people have already read the question and it got dozens of upvotes, which makes it look like it's a good fit for the site even if it's closed.
The biggest problem that can arise from this is if other people come to our site through such a question and think that's on-topic. Or try to argue that many people like it and we should therefore make questions like that on-topic.
We should close questions like that even if they are popular. They are not a good fit for the site and they make people from other sites think that questions like that are the norm on this site.
Just because a question is in the HNQs doesn't mean it's a good fit for the site. Often it's quite the opposite.
