Technical detailsEdit

AnomieBOT is written in Perl, using a custom API class to access the MediaWiki Action API. It uses SQLite or MySQL for persistent data storage.

In addition to the standard "bot" mode which will only run approved tasks, individual tasks may also be run in a "test" mode that logs proposed edits to the local filesystem instead of actually editing Wikipedia or in an "RFBA trial" mode that will automatically stop after a certain number of edits.

Source code is available at User:AnomieBOT/source. The source may be reused under the same terms as Perl, which is currently available under the GPL and/or the Artistic License; the text of the files posted here on-wiki may also be reused per Wikipedia's licensing for text contributions.

Emergency shutoffEdit

Individual tasks may be stopped by writing any non-whitespace content to various pages under User:AnomieBOT III/shutoff/; see the task list below for the specific page corresponding to each task. Many tasks also link the appropriate page from their edit summaries.

Exclusion complianceEdit

This bot is an exclusion compliant bot; see {{bots}} for details.

Bot accountsEdit

AnomieBOT uses multiple accounts for its various tasks:


The full list of tasks for all AnomieBOT bots is at User:AnomieBOT/TaskList.

Task Disable {{bots}} Status Description
DatedCategoryDeleterTest Here  N N/A, only edits bot's/owner's userspace. On hold

None at this time.
