Many times there is a situation on Stack Overflow when the OP does not respond on his/her question.

They ask a question but there is something which should be clearer in the question.

Then someone asks the OP:

How you want it to work?
When you tried with this method, what was the issue? 
Have you tried in this way? 
What exactly you mean?

If the OP does not respond to this type of question, then what was the meaning of asking?

I wanted to know if there is any action to be taken on such type of questions on Stack Overflow.
