    How are they getting spam hyperlinks through my site? Here is my form code...

    <script>
    var proxy = new Array("noonecanstopme.com","blockmeout.co.cc","vvd1.net","sslunblock.com","creditcardproxies.com","hidemyass.com","youhide.com","kproxy.com","delprox.com","unblockall.net","freeanonymousproxy.net","proxytiki.com","unblockingsites.info","proxyforall.com","unblockingwebsites.info","surecloak.com","proxalize.com","burymyip.com","hideandbrowse.com","proxytoorkut.com","anonymityacquired.com","ghostproxy2.com","myprivatestudy.com","bigstorm.info","findawayin.info","sureproxy.com","flyproxy.com","proxyfoxy.com","gingerproxy.com","facebookoxy.com","texasproxy.com","orkutoxy.com","hydme.com","orkutpass.com","proxyguy.com","stealthfinder.com","notyourip.com","myspaceunblocker.com","throughfirewall.com","ibypass.com","officeunblocker.info","webproxyonline.info","proxygiga.com","websitesmuggler.com","firewallfilter.com","digitalproxy.info","zend2.com","proxpark.com","freeproxybrowsing.com","stayincognito.com","blockedsiteaccess.com","surf100.com","unblockfacebook.ca","proxy-service.de","n-pq.de","surfall.net","surfmo.com","cloakmyipnow.info","unblockedtunnel.com","unblockedproxy.net","bypassthat.com","browsemore.info","unrestrictedsurf.net","utopianpal.com","accesstoblockedsites.com","km-proxy.de");
    var proxyMsg = '<b>CANNOT ACCESS SITE<br><br>It appears you are trying to reach this site through a proxy service.

    var proxyFound = false;

    try
    {
    var domain = document.domain.toLowerCase();
    for(x = 0; x < proxy.length; x++) { if(domain.indexOf(proxy[x]) > -1) {proxyFound = true;document.getElementsByTagName('body')[0].innerHTML = proxyMsg; break; } }

    } catch(e) {}
    if(!proxyFound)
    {
    try
    {
    var domain = document.referrer.toLowerCase();
    for(x = 0; x < proxy.length; x++) { if(domain.indexOf(proxy[x]) > -1) {document.getElementsByTagName('body')[0].innerHTML = proxyMsg; break; } }

    } catch(e) {}
    }
    </script>

    Well for a start they could just disable javascript.... Or use http proxys.... Also, it seems your javascript will only prevent those online proxy browsers who use an iframe, any normal person is going to use a http proxy and blow straight on through your protection.
