Subject: Re: [PATCH] graphs.pl: Fixes graph failure when the DROP_HOSTILE directory is missing

The fix technically looks fine. It would have been more elegant to put the strings into a big array and then add only the ones that we need to avoid copying the large block.
However, this is fine for me to be merged.
