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