My question is how to remove duplicate answers, I mean many users just copy the correct answer and post it as their own without even knowing what they have posted. So how can I remove these answers which are exact duplicates of old answers without any modification. For reference take this case- click here

There are so many available answers for this question but they have only one answer-flag for moderator attention.

I have flagged it and moderator found it useful, screenshot of it is as

enter image description here

Even one answer's code is also not correct because he removed ` from my code which made it full of error.

Now my question is if the moderator accepted these two flags then why aren't these duplicate answers removed?

Did you consider that, since the answer in question is just a single line of bog-standard SQL code, two people could have independently posted the exact same answer to the question? –  Cody Gray Apr 17 '12 at 5:56
    
But the last two answers are just copy paste of my answer, nothing new in them –  Ankit Sharma Apr 17 '12 at 6:08

Obviously you still haven't considered that... And let's try to tone down the accusations, eh? It's fairly offensive to accuse people of copy-pasting your answer without any evidence that they've actually done so. The fact that the answers are similar does not count as evidence. –  Cody Gray Apr 17 '12 at 6:11
    
@TheEstablishment but you can see the screen shot that moderator is also agree to me. –  Ankit Sharma Apr 17 '12 at 6:14

No, they just marked your flag as helpful. That doesn't mean that they agree the answers were duplicates. They were probably hoping to keep you from running to Meta complaining that your flag was declined. Oh well, live and learn. –  Cody Gray Apr 17 '12 at 6:15

@jason not all helpful flags garner action –  simchona Apr 17 '12 at 6:16
    
@simchona then what is the profit to mark them helpful if they didnot deserve an action. –  Ankit Sharma Apr 17 '12 at 6:19
    
Mods mark flags as helpful even if they're not going to take action. Since I'm not a mod I can't say what they're thinking, but I hazard the guess that they said it was helpful, looked into it, and did what they thought best. –  simchona Apr 17 '12 at 6:19
    
Wow, it's like my comments don't even get read. The next question is inevitably something I just answered. –  Cody Gray Apr 17 '12 at 6:20

@theestablishment I'm reading them. –  simchona Apr 17 '12 at 6:22
    
It's getting difficult to understand your English. If you're not going to consider what I or @theestablishment said, I'm not wasting my time fighting with you. –  simchona Apr 17 '12 at 6:26

@TheEstablishment but this attitude is wrong if the flag is marked as helpful just to remove the chance of further cumplain' –  Ankit Sharma Apr 17 '12 at 6:29
    
I see. I'll let all the SO moderators know to mark your flags as "declined" from now on. –  Cody Gray Apr 17 '12 at 6:30
    
@jason then that's a different question. You might want to know that The Establishment is a mod. He knows things. –  simchona Apr 17 '12 at 6:32
    
@simchona i didnot interested to know if establishment is a mod or not, i am just want the exect reason for this topic, thats it......and i didnot want to fight at all and sorry for my bad english. –  Ankit Sharma Apr 17 '12 at 6:35

Is that answer even correct? I'm not a MySQL expert, but I do know "from" is a reserved key word, and I'm not sure if that query will run with the word not enclosed in backticks like that.

Anyways, moderators aren't required to take action on a flag. They can dismiss flags as helpful and they're actually encouraged to do so in cases where the user was legitimately attempting to be helpful.

As for duplicated content, it is a very borderline issue. Likely the moderator who reviewed your flag didn't feel comfortable deleting the post.

In my answer i am using `` in from but the other poster doesnot done that he just copied my answer and removed ` without even understanding the real fact of using ` –  Ankit Sharma Apr 17 '12 at 6:09
    
@jason stop making accusations. Simple code can be thought of independently. –  simchona Apr 17 '12 at 6:13
    
@simchona yes i know that simple and even complicated code can be though independently but the syntex is exect duplicate in this case and i didnot think it as a coincident. –  Ankit Sharma Apr 17 '12 at 6:17
    
@jason the syntax is rather hard to deviate from. –  simchona Apr 17 '12 at 6:18
    
@simchona a have not answerd that question that fast , i have done tha similar question previously and i have took too much time to reach on the exect code, so i didnot think the other two have done any hard work to do so because one answer is juct appear after mine and is must not be a coincident –  Ankit Sharma Apr 17 '12 at 6:23
    
@jason So because you think you thought of it first, they didn't do any hard work? Your answer got accepted. What's the issue? –  simchona Apr 17 '12 at 6:24
    
@simchona issue is that how to remove duplicte answer? as you can read it in title –  Ankit Sharma Apr 17 '12 at 6:26
    
They're not necessarily duplicates of your answer. It's not illegal to have similar code. Deal with it. –  simchona Apr 17 '12 at 6:27

You might be interested in reading up on the cum hoc ergo propter hoc logical fallacy. This is where one assumes that because two events have a temporal relationship, that one caused or is related to the other. That's what happened here: two people posted similar answers to a question on Stack Overflow, and you're committing a logical fallacy by assuming/accusing them of having copied your answer just because you both posted it within a similar period of time. You might also consider getting on with your life. –  Cody Gray Apr 17 '12 at 6:29
    
@The: post hoc ergo... –  Josh Caswell Apr 17 '12 at 6:31

YES YOU'RE RIGHT IT TURNS OUT THAT THE ENTIRE STACK OVERFLOW SYSTEM IS BROKEN BECAUSE A "DUPLICATE" ANSWER WAS NOT DELETED. WHAT HAPPENED TO YOU HERE HAS OPENED UP A WORMHOLE IN THE UNIVERSE. COLLAPSE IS IMMINENT. RUN FOR THE HILLS!! –  Cody Gray Apr 17 '12 at 6:33
    
@jason Duplicate questions have a wide gap of time when one is clearly linked to the other. Duplicate answers is based on the assumption that the answers are actually duplicates. Which doesn't seem to be true here. –  simchona Apr 17 '12 at 6:33
    
@simchona thanx for talking time for polite conversation. Now i got my answer. –  Ankit Sharma Apr 17 '12 at 6:39
    
+1 for being the only answer –  Ankit Sharma Apr 17 '12 at 8:06
