The Reseller's Revenge

I was just a small-time online reseller, a ghost in the digital marketplace, until a single message ignited a war. He called me stupid, a waste of his time. He didn't know he was insulting the one person who could dismantle his entire illegal empire, one click at a time. He thought he was a king ruling his shady corner of the internet, but he forgot that even kings can be toppled by a ghost with a grudge and a deep understanding of the rules. My revenge won't be loud, but it will be devastating.
