Thanks.  I spot-checked four, and all were registered one
year ago, and are now expiring.  The nameservers I saw were:

      ns4.dnsdun.com
      ns4.dnsdun.net
      ns1.dns.com
      ns2.dns.com
      ns1.dnsfang.com
      ns2.dnsfang.com
      v1s1.xundns.com
      v1s2.xundns.com

The first two had the same registrant, all four registrants
had mainland China addresses.  So something unusual started
a year ago, ... but probably not worth pursuing further if
not immediately clear what...
