  11 # NOTE Bad robots detection is based on checking elements easily
  12 #      controlled by the client. As such a determined attacked can bypass
  13 #      those checks. Therefore bad robots detection should not be viewed as
  14 #      a security mechanism against targeted attacks but rather as a nuisance
  15 #      reduction, eliminating most of the random attacks against your web
  16 #      site.
