Can you edit your answer to something completely different after you get Best Answer, to make the asker of the question look like a complete idiot?

@HairbrushDiva For example, someone posts something very opinionated and specific and you comment something which they agree to, adding more info, which is why they give you BA. Then you change your answer to the total opposite of their post, but they've already given you BA. They'll get trolled for it

@Nomad7 I'm an anti-troll, so why should I do anything that encourages trolling?

@HairbrushDiva You're English, I forgot. That's a nice way of saying you're no fun

@Nomad7 See, you are deliberately trolling me now.

@HairbrushDiva No, but you seem nice

@Nomad7 I try to be.
