It's infuriating to have a comment deleted. It's happened to me at least twice (that I remember) when something was selected as the correct answer but it turned out to be wrong. In one case, the answer was specific to Windows and a range of releases of the language. I posted my comment, it got deleted, I reposted, and it got deleted again. In another case, the answer marked correct didn't work and wasn't even a full answer - the provided code showed how to start the solution and left the rest as an exercise for the reader. When I commented that the answer was wrong (even the part that was given) my comment simply disappeared without explanation.
