What is meta?
Here's how it works:
  1. Any Stack Exchange user can ask a question
  2. The community provides support, votes on ideas, and reports bugs
  3. Your voice helps shape the way Stack Exchange operates

What should be done with accepted, yet wrong, answers?

In this particular case the OP accepted an answer that, by all means, was wrong. And when I say "wrong," I don't mean that it could be done by a better approach. I mean simple, plain, wrong.

More on that: the user was warned in advance that the answer was wrong.

Clearly, this devalues the site.

How should one act upon answers like this? Flag them for moderation?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

This reminds me about why I created an account and got active on stackoverflow (a security bug in the second answers of ) – Hendrik Brummermann Oct 12 '10 at 7:01

You've already done the right thing - pointed out it's wrong and that's tracked in the comments as well as updated by the answerer. The answerer has asked for his answer to be unaccepted.

Additionally you could downvote it to register your protest ;)

That's the only way you get incorrect answers floating downwards


As @Tobias has pointed out, accepted answers will remain on top. But a negative score would discredit it.

an (not self-)accepted answer will remain on the top and not float down. But of course seeing an accepted answer with negative score will hopefully raise enough suspicion to make the reader think twice – Tobias Kienzler Oct 12 '10 at 7:32

I believe that an answer, once it's been accepted/voted on/has comments isn't deletable by the OP anymore however, it might be deletable by a moderator. Therefore you could try putting a comment against the answer suggesting that it's wrong and that the OP (of the answer) flag for moderator attention to have it deleted.

Not everyone will respond to the comment or flag for moderator attention, but it might be worth a shot?

Alternatively, you could suggest that the OP of the answer prefix their answer with a note stating they actually believe it to be wrong.
