Stats on August’s deleted blog comments

In the interests of openness, we have compiled statistics for the posts we have deleted from the blog last month, August 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 August. All deleted comments were spam.

In total the site received 366 comments in August, 113 were automatically removed by spam software, and we have deleted 26, so just over 10 percent of them. This is a lower figure that usual, but even so it is notable that the number of spam comments received by the blog has rocketed. This we believe is for two reasons: the blog has become increasingly visible and so has been targeted more by spammers; and secondly, we recently upgraded our blog software and spammers have been attempting to break the anti-spam systems in place with this software version.

The good news is that we have also had an increase of real comments and at the same time none of them broke the comment policy, so none were deleted. This can only be positive in terms of greater community dialogue.

    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."
