Well from one point of view I agree but I have been in a similar case in the past where although I had done really hard work and research on my problem I was not able to found the solution.

That's the key, there. You were putting in the study and effort, and that would have been shown in the quality of questions you can ask about the problem.

A half-decently written spambot is capable of repeatedly spewing semi-randomized problem quotes and Markov chain titles together. We need to demand better from humans.
