Fellow Monks, lend me your ears...

I'm trying to write an urlgrabber and I thought it would be nice to include a sort of blacklisting system with it. Now the code for the grabbing/webscraping works perfectly. But I'm having problems with the blacklisting system.

I have 2 arrays. One (@sites) contains the grabbed urls, the other one (@blacklist) contains the blacklisted keywords. Now the code I came up with does "kinda" spot the blacklisted urls, but is clumsy, slow, inefficient and has to be filtered.

Could anyone point out an easier (and faster) way? 

#!/usr/bin/perl
# example blacklisting

@sites = (
    "http://www.rtfm.com", "http://www.alottatax.com",
    "http://www.kingdom.com/cgi-bin/script.pl"
);

@blacklist = ( "cgi", "blabla", "testme" );

foreach $site (@sites) {
    &blacklist();
}

sub blacklist {
    foreach $blacklist (@blacklist) {
        if ( $site =~ m/$blacklist/gi ) {
            print "$site blacklisted - $blacklist\n";
        }
        else {
            print "$site ok\n";
        }
    }
}

I'm sure there's more than one way, but /me just needs one anyway - Teabag
