There is a question that I answered a while back, that I find myself looking at every now and then. Recently I noticed something that changed about the accepted answer. Here is the question:
The original accepted answer was answered in early 2012. The originally answer was approximately 300 characters in length. The answer was simple and straightforward. The OP liked the answer enough to accept it.
Then, nearly 3 years later (Nov 2015), the accepted answer is significantly edited by the original user who wrote it. The new accepted answer is now approx 2500 characters. An approx 850% increase in size. Big change:
Here are the revisions:
Should answers that are altered this much be flagged or rolled back or something? When someone specifically marks and answer as accepted, and then later the answer is changed so much that it hardly reflects the original answer, is it still the right answer? Would the original person who asked the question still accept it in it's current form? The question was asked so long ago, who knows if the original poster ever even came back to see the heavily revised answer?
I thought it was a weird situation that I have never noticed before. I don't know if this is something that is acceptable or not. At the same time, in this case the original answer was heavily expanded on, not necessarily heavily altered itself. So maybe it's not a bad thing. Or maybe it's misleading. Maybe the original poster accepted it because it was originally a short, simple and straightforward answer. It's definitely not short anymore. I dunno. Just reaching out to see if there are opinions on this topic or not.
