standard for robot exclusion
     
         A proposal to try to prevent the havoc
        wreaked by many of the early {World-Wide Web} {robots} when
        they retrieved documents too rapidly or retrieved documents
        that had side effects (such as voting).  The proposed standard
        for robot exclusion offers a solution to these problems.
