--- layout: post title: "Introducing Stalker: Nickname History For Irssi" author: "Geert Hauwaerts" email: "geert@irssi.org" --- Stalker is an Irssi plugin to correlate information on an IRC network and discover users' previously used nicknames. The concept is fairly straightforward: given a nickname identify previously used hostnames. From those hostnames, extract all nicknames they have used. Repeat until you have identified all nicknames a user might have used. The advantage of this method over the more traditional "given a hostname identify all nicknames it has used" is that you can identify nicknames across hostmask addresses. Stalker can be found on GitHub at [http://github.com/symkat/Stalker](http://github.com/symkat/Stalker).
