Take a look at domains in www.whois.sc and you will find that they not only publish information about the site, but also the OS on which the site is running, the web server, version numbers - everything. It doesn't seem to me that they should be publishing this information without explicit permission from the web site owners. Once someone knows what operating system you run and the software you are running on it they are able to eliminate a great deal of work in the number of exploits they have to try to get a result. They can go for blood out of the gate for holes in those known types of software.
Oh and by the way now your system information is searchable, making it easier for hackers to find all the sites that run PHP for instance...
If I were you, I would recommend that you request removal from this database:
Of course they provide no way to contact them on their web site without creating an account. Isn't that lovely. Therefore I looked up the DNS records and drilled down first using the whois on DNSStuff.com which led me to this address:
However if you look up the domain name records using the DNS Lookup Tool on the right side of the screen you get:
cluster.nameintel.com. A IN 300 18.104.22.168
nameintel.com. NS IN 86400 ns1.dnscloud.com.
nameintel.com. NS IN 86400 ns2.dnscloud.com.
ns1.dnscloud.com. A IN 3600 22.214.171.124
ns2.dnscloud.com. A IN 3600 126.96.36.199
The contact for this particular set of domain records is:

Hmm I wonder if they like this being published?
