I have a Perl program on my server to prevent certain words being used when my contact form is submitted. For the most part it is working but a single "spammer" has somehow found a way around it. Here is the code.

$String=param('Message');

if ($String =~ /porn/) {

print "<p><font size=+4\">Goodbye</font></p>";
exit;}

if ($String =~ /sex/) {
print "<p><font size=+4\">Goodbye</font></p>";
exit;}

if ($String =~ /girls/ ) {
print "<p><font size=+4\">Goodbye</font></p>";
exit;}

The rest of the program checks for "Not a Robot", Enter Anti Spam number, etc and then forwards the message to my email service. When I get an inappropriate message I can copy it and paste in my contact form and the message will not be sent, i.e. I get a "Goodbye" return. How can this be? How is the spammer getting by my safeguards?

Any and all help will be appreciated. Tks!

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
