Depending on the needs, this method is a bit too strict, as it will reject even compound words that contain a offensive word as a subword.

A way that could also be worked around, but which would create less false positives, would be to make sure each offensive word is used as a word alone :

my $badwordsRE = "\\b" . join( "\\b|\\b", @badwords ) . "\\b";

reject if /$badwordsRE/o;

My advice to the original poster is to get a list of offensive words from the web master administrator or some other person responsible for that thing and use that list as a ban list - so he is clean with them. If there is no such list, then I wouldn't censor at all.

perl -MHTTP::Daemon -MHTTP::Response -MLWP::Simple -e ' ;    # The  
$d = new HTTP::Daemon and fork and getprint $d->url and exit;#spider
($c = $d->accept())->get_request(); $c->send_response( new   #in the
HTTP::Response(200,$_,$_,qq(Just another Perl hacker\n))); ' #  web

It might be a good idea to use the /i modifier as well - it's OK to block 'smurf' and 'fork', but what about 'SMURF'...
