Any chance you'd consider Python for this? It has built-in CSV support; I don't know much about Perl.
This doesn't really resolve the problem or offer a meaningful path to go down in most situations. As a moderator, I agreed it was not constructive and removed it to clear the flag. We see several dozen of these in the queue every morning, it was one of many removed as a normal processing of the moderator flag queue.
We aren't perfect on cleaning up any replies to comments removed (we don't have a great deal of visibility when dealing with things en masse here), the error here was leaving that reply behind when it made no sense...it's been removed to clean up as well now.
