How do you know if a question is really seeking an answer?

Question

Or is just a sucker question from the trolls?

Answer 1

Usually by the tone and the way it's worded. A polite, open minded question will probably be genuine, an aggressive or ranting one will most likely be posted by a troll.

Sometimes people post sarcastic or ironic questions in response to a previous post... I guess the only way to tell is if you know the asker; once you've been here a while, you get to know everyone's stance and you can usually tell if they're joking.
