Description

As per [0], a FTP website can have robots.txt like [1]. In the nutch code, Ftp plugin is not parsing the robots file and accepting all urls.

In "src/plugin/protocol-ftp/src/java/org/apache/nutch/protocol/ftp/Ftp.java"

   public RobotRules getRobotRules(Text url, CrawlDatum datum) {
    return EmptyRobotRules.RULES;
  }

Its not clear of this was part of design or if its a bug.
