This question already has an answer here:
I was looking through a list of wpf questions with 0 answers and found this one:
The caveat here is that in the list, it showed 0 answers but had the markup as if one of the 0 answers was accepted. Intrigued, I clicked and discovered that this answer: https://stackoverflow.com/a/1931696/1026459 (10k+ req to view) had been deleted.
The deleted answer was accepted (although it is not very high quality). Or the accepted answer was deleted. One of the two happened, but I was not sure how. I tried it on one of my own accepted answers and was denied with the message "You cannot delete this accepted answer".
How did the linked accepted answer get deleted?
