Opinions of this proposal?
I would love to have a listing of recently registered .cn domains but
until the TLD operator starts working with us that just isn't going to
happen.
Trying to perform a whois lookup on every domain is painfully slow.
Once you get a high enough volume of .cn domains detected it will become
impossible and that is assuming you are never rate limited. On top of
that, most of the time when I do a whois lookup on a .cn domain I find
the destination whois server to be unresponsive, stuck in a "maintenance
mode" or doesn't include any data except the domain name and the listed
nameservers.
Spam from .cn domains can be mitigated with the right rules and querying
multiple lists. I know my users never see .cn domains in their inbox
and if I didn't run a blacklist I wouldn't either.
Instead of blacklisting new domains (which is apparently difficult to
do), why not blacklist all .cn domains (or simply all domains) newer
than xxx days?
If they're older than xxx days and not yet on another blacklist for
sending actual spam, return a neutral response.
