Thottbot is an unofficial Worl of Warcraft plug-in and database website. The plug-in, which is programmed in Lua, collects information while a person is playing the game — such as the drop rates of items, locations of specific mobs, and quest information — and users then upload the information to the website's database. The information on the website only comes from players using the plug-in and who take the time to upload the data. Simon Carless of Gamasutra described Thottbot as a "major item listing site." As of March 9, 2008, web traffic company Alexa reported that Thottbot.com was the 250th most visited site on the internet.
