I deleted the answer.
Normally I'll post a comment explaining, "Please don't post the same exact answer to multiple questions. If they are duplicates, flag or vote to close them as such. If they are not, then please tailor your answer to the specific question asked."
During the course of moderating at that particular point, I had already cleaned up at least five such different occurrences by different users.
It's one of the more annoying things to moderate because in the course of moderating that content, you have to do the following:
- Check all questions the user posted their duplicated answer to, to see if the questions are duplicates.
- Find the oldest question (or the question that has the best answers / most views), and use that as the 'canonical question'.
- Close all the questions that are duplicates of that question.
- Delete all instances where that user spammed their answer and that question was closed as a duplicate.
- Leave at least one comment to the user who did it to remind them, "Hey, you really shouldn't be doing this."
In this particular case, I didn't do the last step. I was somewhat frustrated at that point and had the view, "Hey, this user knows what they did. If it's deleted, then they'll realize they probably shouldn't have done what they did."
It wasn't really right for me to do that. I should have left a comment for the user, on the chance that they didn't realize it's a 'no-no' to post duplicate answers.
Really, the system already flags it when a user does that, so the system should take it one step further and automatically warn a user when they're about to post duplicate content. Maybe something like the following?
Please don't post the same exact answer to multiple questions. If they
are duplicates, flag or vote to close them as such. If they are not,
then please tailor your answer to the specific question asked.
I'd even go so far as to say that the system should not allow duplicate content, but I'll take what I can get.
