The current default value of $wgDnsBlacklistUrls is [ 'http.dnsbl.sorbs.net.', ].
However, according to sorbs.net, they have terminated the service and all queries will return NXDOMAIN. Having such a default value is now meaningless, and does not block any spams. Replacing it with empty can avoid some users still using sorbs.net continue querying SORBS.
Note that this default value is also used on some WMF wikis:
- wmf-config/CommonSettings-labs.php (1 matches)
- wmf-config/InitialiseSettings.php (1 matches)
