Sorry about the two questions in the same day but this is really bugging me. I have a form which I'm using but of course I underestimated the maturity of the people who use it and I got a lot of people tossing in swear words on the sign up form *sigh*.

I tried adding a word filter but when I added it the filter blocked EVERYTHING, even things that weren't in the @ignore didn't go through. Ugh, I am getting frustrated with this one. Why is it blocking things I'm not asking it to?

if(param()){
    my $username  = param('username');
    $username =~ s/\s+\z//;
    my $askname   = param('askname');
    $askname =~ s/\s+\z//;    
    my $update = param('update');   
    
    if($username){
        if($askname){
        
            if(grep($username, @ignore) || grep($askname, @ignore)) {
                print "That didn't quite work";
                exit;
                }
        
            if($update eq "add"){
                if(exists $list{$username}){
                    print "Username already exists in database.\n";
                    }
                else{
                    $list{$username} = $askname;
                    print "Username was added to our system!<p>\n";

                }
            }
            elsif($update eq "rem"){
                if(exists $list{$username}){
                    delete $list{$username};
                    print "Account information was removed from the sy
+stem.\n";
                    }
                else{
                    print "Oops, it doesn't appear that username is in
+ our database.\n";
                }
            }
        }
        else{
            print "For this to work please add your username.\n";
        }
    }else{
        print "Unless your name is null, please go back and fill it in
+.\n";
    }
}

            print end_html();
