Some questions and suggestions about the WHOIS Misuse study

[Nacer Adamou Saidou <adamou.nacer@xxxxxxxxx>]

Hi,
At first, I want to congratulate all the parties for this excellent job.
My first question is about the duration of the experiment: 6 months. How was 
this duration determined?
My second question is about the fact that the gTLD is "the sole 
statistically-significant characteristic that affects the occurrence of the 
associated misuse of phone numbers published in WHOIS". What explanation could 
you provide for this correlation? Is it due to the reputation of the 
corresponding gTLD?
And similarly, you stated that the price of the domain name is negatively 
correlated with the possibility of misuse of email addresses published in 
WHOIS. can we extrapolate by saying that this is due to the availability of 
additional services (like proxy/privacy services and other) provided with the 
domain name?

Finally, as this study seems to be very informative, I suggest that the GNSO 
supporting organization build a toolset for a continuous monitoring of WHOIS 
misuse reported incidents so that such information would be available for 
decision making.

Best Regards
