I wish I knew about this. I wrote a file server that serves your webroot directory over League of Legends chat. Any time you request a file that is more than a few bytes, your chat gets flooded with base64 strings... The extraslow web.
Heh, I once wrote a piece of software that would read World of Warcraft's memory space, scan for the chat circular buffer and then post new guild chat messages to twitter.
At first my guild mates loved it - but then it created some guild internal drama as some "officers" were having a rather not nice chat about other guild members in the night and they thought they were alone.
Pretty much destroyed my guild. But at least I could finally say "What have I done!" and mean it ;)
I'm not really sure if it's within the rules of the game, so there will probably be no video, but I'll probably github the source soon. It's Node based, but some of the dependencies are a pain to set up.
