Stats on September’s deleted blog comments

In the interests of openness, we have compiled statistics for the posts we have deleted from the blog last month, September 2007, broken down according to person and type of comment. We have only listed those who had three or more comments deleted. There was no individuals at all that had comments deleted in September. All deleted comments were spam.

In total the site received 1538 comments in September, 1409 were automatically removed by spam software, and we have deleted 73, so just under 5 percent of them. As can be clearly seen, the spam problem continues to escalate. Our spam filters have been slightly more efficient this month, but thanks to the overall trebling of spam in just one month, we are now manually deleted more than two spam comments per day. We will continue reviewing our anti-spam approaches to see if we can cut it back further.

On a more positive note, for the second month in a row there was no need to delete any normal comments. There were several posts this month that covered subjects where people have strongly held and sometimes opposing views, so we are delighted that that conversation managed to happen without spilling over and breaking the comment policy.

    Domain Name System
    Internationalized Domain Name ,IDN,"IDNs are domain names that include characters used in the local representation of languages that are not written with the twenty-six letters of the basic Latin alphabet ""a-z"". An IDN can contain Latin letters with diacritical marks, as required by many European languages, or may consist of characters from non-Latin scripts such as Arabic or Chinese. Many languages also use other types of digits than the European ""0-9"". The basic Latin alphabet together with the European-Arabic digits are, for the purpose of domain names, termed ""ASCII characters"" (ASCII = American Standard Code for Information Interchange). These are also included in the broader range of ""Unicode characters"" that provides the basis for IDNs. The ""hostname rule"" requires that all domain names of the type under consideration here are stored in the DNS using only the ASCII characters listed above, with the one further addition of the hyphen ""-"". The Unicode form of an IDN therefore requires special encoding before it is entered into the DNS. The following terminology is used when distinguishing between these forms: A domain name consists of a series of ""labels"" (separated by ""dots""). The ASCII form of an IDN label is termed an ""A-label"". All operations defined in the DNS protocol use A-labels exclusively. The Unicode form, which a user expects to be displayed, is termed a ""U-label"". The difference may be illustrated with the Hindi word for ""test"" — परीका — appearing here as a U-label would (in the Devanagari script). A special form of ""ASCII compatible encoding"" (abbreviated ACE) is applied to this to produce the corresponding A-label: xn--11b5bs1di. A domain name that only includes ASCII letters, digits, and hyphens is termed an ""LDH label"". Although the definitions of A-labels and LDH-labels overlap, a name consisting exclusively of LDH labels, such as""icann.org"" is not an IDN."
