Perhaps it would be a good idea, if the blank pages would be template-based, so you can edit them and display some warnings and at least an email-adress to the webmaster.
I don't want to exclude silly users forever.
Another thing I found: A user posted a thread in the forum containing sample code concerning REWRITE with some *. But this user was listed as guest in the Protect Center.
I wonder what is happening here if I poste the code? Here is the thread:
Moin,
folgenden Kram
RewriteEngine On
RewriteCond %{HTTP_REFERER} !^http://DeineDomain.de/ [NC]
RewriteCond %{HTTP_REFERER} !^http://www.DeineDomain.de/ [NC]
RewriteRule /*
http://www.DeineDomain.de/index.html [R,L]
in eine .htaccess packen und in den Bildordner der Galerie laden. Bei installiertem mod_rewrite werden die "Backdoor-Heinis" wieder zur Startseite geschickt oder Du bastelst eine nette Seite mit nem Fehlertext...
