RationalWiki uses $wgEnableDnsBlacklist = true; and
$wgDnsBlacklistUrls. We presently have
xbl.spamhaus.org,
dnsbl.tornevall.org and
all.s5h.net in there. These are pretty good,
but of course run on several hours' delay from the fresh proxy lists.
What we could really do with is one of webhosting ranges - we have a
plague of G*m*rg*t* trolls who favour coming in through these (pwned
boxes, I presume). Does anyone maintain an RBL of these?
