I have seen some questions that just stand out as not belonging in WB (nor Stack Exchange, nor any other Q&A sites) and that have one characteristic in common: they seem to be coming from a (possibly young) men with low or no empathy for others, and whose world view was probably developed by watching animated pornography.
The first time around it was someone who came to WB to ask where to find prostitutes. That was the whole question, and yet instead of voting to close, I saw people recommending to the OP that he should go through the tour and edit the question to be more in line with the construction of a fictional world. That one was deleted so I cannot find it in search, but I remember it only went downhill from where it started.
Remember when we just had to discuss whether making rape more demoralizing was cool? Oh how much fun we had... Not. That was the second time I think we took too long to nuke a question. The offending question had ten downvotes but not a single vote to close when I found it. It's almost as if we were collectively saying "that's a nasty one, but I do want to see an answer to it yet".
Third time is the charm, so now we have a question about whether a humanoid can thrive on semen. It has 10 downvotes but only a single VTC.
Come on, people. Check the edit history for the first form of the question. It was about how much sperm you need to feed a person. If you really want to take a detached, scientific view you are only a couple Google searches away from finding out. If you had decent biology classes at high school you probably don't even need that.
If you want to take a worldbuilding view, though, where you have a fantasy race that feeds on whatever, you might as well ask "can elves feed on mana and how much do they need". Or "can my pixies thrive on soma", or "can unicorns survive on a diet of rainbows". It's your world, with your fictional creatures, so you tell us whether that works or not. So making the question in point more worldbuildy did not turn it into a viable question.
Can we just agree that these questions are not about building a world, so that we can properly close them when they pop around?
