Methods and systems for managing or regulating offer listings in an electronic marketplace. Consumer feedback regarding the offer listings may be received and analyzed to generate recommended or candidate rules. The recommended rules may be presented to rule authors for validation. Acceptance and/or rejection of the recommended rules can be used to train or otherwise improve the generation of future recommended rules. The accepted recommended rules can be used to generate final rules. The final rules may be applied to offer listings to trigger a variety of actions including filtering of offer listings, sending notifications to sellers, and updating offer listings user interface.
