See: this answer to Does .net equal C#?. I flagged it as "not an answer", and said flag was rejected. The text says "flags should not be used to indicate technical inaccuracies, or an altogether wrong answer".
Now, if the answer were merely wrong, I wouldn't have flagged it. But the answer refers to Lisp, C, Python, Ruby....pretty much everything BUT .net or C#. How does this qualify as an answer to the question?
And assuming someone agrees with me here, how do I get my flag weight back? :P
