High Level Duck Journal
The Duck Journal tracks, among other things, 'Duck XP' which is a form of scoring based on creating duck drops and picking up dropped ducks.
The number shown here is extermly high and almost impossible to achieve in a normal way.
After EOTL came out, someone made a plugin that let you spawn lots of ducks. This plugin was up on AlliedModders forum for a bit. Anyone that got ahold of this plugin could rapidly spawn ducks and in the process manimulate the Duck XP level.
Valve took notice of this plugin and they told the person to remove it from the site disallowed the publication of it.
