Or you can simply add a few lines into your perl code, such as:
use LWP::Simple;
$html = get("http://bla.com/members/xxx/autosubmit/01.html");
if ("$html" =~ /UNWANTED SHIT/) {
print(" go fuck yourself ");
$ABORT=1;
} else {
print("have a nice day\n");
&add_listing;
}
To expand on this, just place your unwanted functions in a text file, one per line. Read in the file and compare each line with what is in the html.
thats what i do on
