In forums or groups on social media, I saw some people pop in and say something like that.
This is a bad form, for several reasons. What the person is actually asking here is
There are plenty of reasons why people DO have the knowledge would NOT admit to it. The unclear question proves your laziness. Why people should do the work to solve your problem if you’re not willing to do it?
Some people send me a message then stop there until I reply.
Hey, I have a question.
Alo, I have a bug.
They only describe their problems until I ask them to clarify them.

This is also a bad form. Why not jump into your problem so I don’t need to ask an extra question.
Hey, I’m reading [book] and I’m confused with the [concept]. Could you have time to explain it to me?
The point here is not to ask, just ask.
