Most users of the OpenCyc Web Interface will not use the SubL Interactor. The SubL interactor allows arbitrary SubL forms to be evaluated by the OpenCyc application. The evaluated forms are not limited in any way, so it is quite possible for mistakes to crash the application, or to corrupt its datastructures. Most Cyc operations are better handled by one of the Web Interface's other facilities.

The SubL interactor also introduces a security weakness: SubL is a general-purpose programming language which includes functions for reading and writing files, so the entire network accessible to the Cyc Server is potentially compromised. Machines running Cyc should be on a secure internal net.
