It matters because it is Tilly's work (despite what his employers may or may not think about it) which has been plagiarised and hence he has a right to know. Perlmonks was the method of dissemination and therefore we have a duty to inform him, or at the least the administrators of this site (id est the Gods) should consider doing so if they think that it won't irritate the hell out of him - considering the vast amount of really damn'd useful stuff he contributed during his time here, I think that it would be the conscientious thing to do. The size of the script is fairly irrelevant IMHO because it is not central to the misdemeanor, namely that the kid passed off work as his own when it was not.
