Additional information. The bleached script should have header like: === use Acme::Bleach; === instead of === $_=<<'';y;\r\n;;d;$_=pack'b*',$_;$_=eval;$@&&die$@;$_ === So this might not a bleach script. More study needed.

Btw, I don't know script author. He/she might hide contact information inside script.:-)
