The classic of course is the ubiquitous Stack Overflow Q&A that goes:
"I'm trying to do X, is there a way to make Y do it?"
"Why on Earth would you want to do X?"
On the other hand even that one can be warranted, as people have a bad pattern of looking for solutions to their incidental problem at hand rather than stepping back and looking at reaching their actual goal.
On the other other hand, the above happens even when people show their work and explain the circumstances that make their problem essential to the goal.
