This bot patrols newly created pages in the main space, and matches the contents against a web search. Pages found to contain a significant portion of text taken from another web page are tagged (and categorized) for human attention according to some guidelines:
If the 'bot modifies the newly created page in any way, then it will also leave a message on the creator's talk page, and on suspected copyright violations to bring attention to the apparent problem.
Additionally, the 'bot watches and/or updates a number of subpages under its user page for runtime configuration, directives and status information.
The CorenSearchBot is meant to function continuously, without direct human supervision.
The source code can be perused here, but it's not pretty.
