I recently posted this question: Color picker that sends events per color pick and a certain user posted an "answer" which he obviously did not test or compile.
Upon saying that his answer did not compile or even look near right, he attempted to correct it. However, not only did not even compile, it was once again, not even near the right path. After asking him about this in the question, he deleted the response.
Now I know I don't have enough rep here as I am new, but this kind of behavior is just not acceptable. It is very poor behavior on his part and very negatively reflects Stack Overflow. How will I know I will ever get helped when people like him are around? How many of his responses are just spam?
