StealthBot is a classic Battle.net chat bot, written in Visual Basic 6, and originally developed by Stealth (Andy T). My first involvement with the project was as a beta tester around 2006, but I was quickly brought on board the technical support team, eventually being made the support team administrator, and I ultimately joined the project as a co-developer in 2008.
Recent updates to the classic Battle.net platform have left the application largely irrelevant to modern needs, and it is no longer being officially maintained. The website has also ceased to function, and so it can only be found on GitHub.
