We've been suffering an attack from a vandalbot written specially for us which appears to hop from open proxy to open proxy. So I've had to disable editing through an open proxy, using the following lines in LocalSettings.php:
$wgEnableDnsBlacklist = true;
$wgDnsBlacklistUrls = array( 'xbl.spamhaus.org', 'opm.tornevall.org' );
Ordinary not-logged-in IP-number editors should be able to edit and remonstrate with us over our ignorance in the usual manner, per the invitation to do so on the front page (and have been doing so).
Note that I think the open proxy block also affects logged-in users. If you are a regular RW editor and this is a serious problem for you, please email David.
This only affects English RationalWiki, not Russian RationalWiki .
Editing through an ordinary non-anonymous proxy (your work or ISP) is fine.
