This feature is very helpful when searching for members with multiple accounts. Many times spammers will create multiple accounts which contain different variations of the same word within their usernames. For example, the infamous PHP-Nuke Lottery spammer is a person or group of people that target PHP-Nuke websites and exploit the web mail features to send out loads of Spam email from the victim's website. These spammers commonly use the word lotto in their usernames. This search feature makes it easy to seek them out if they exist in your database.
