Thanks Kim, nice link.

It might be worth noting that these results are undoubtedly related  
to registry technology used as well as  policy or price.

By way of example, .tk uses a database drive DNS servers (powerDNS i  
believe) which allows registrants to instantly modify the A/MX  
records without waiting for zone builds. TLDs which generate zones  
once or twice a day are not overly interesting to scammers. In the  
case of Christmas Island (which has quite a high rating given its  
size)  similar data is being monitored for us by PCH and results are  
skewed by the large number of domains in two stub zones which give  
away free 3rd level .CX domains and utilize dynamic DNS services.

In  cases where registrants register a second level name and then  
give away free third level domains (and include free URL forwarding  
or DYN DNS ) the registry policy and price would not impact the  
results. As always caution should be exercised when looking at  
statistics.

Cheers,

Garth
