Yester-day evening, I was using a publicly accessible WLAN to connect with the Internet. I found my access to this 'blog blocked by a Norton-branded product, which declared the 'blog to be pornographic.

Erotica really hasn't figured large in this 'blog. You can find the relevant entries with the tag erotica. I think that the two or three entries that caused Norton to damn this thing are specifically my entry of 2 July 2009, my entry of 26 March 2010, and perhaps my entry of 30 June 2010; the entry of 30 January 2011 may have weighed against me as well.

Of these, the entry of 2 July 2009 is the one that most likely set-off alarms. It contains an overtly erotic image (by Carolyn Weltman), and has a key-word of cunnilinctus.[1] Do a Google image-search using that key-word, and a link to that entry is currently the second returned. And, because of a couple of the other key-words in that entry, other images are also found, including one by Karel Šimůnek than many would regard as pornographic.

In the '50s, the drawings by Joe Shuster in the entry of 30 June 2011 would have been regarded as pornographic, though now the word pornography would typically be regarded as too strong. (Actually, a hundred years ago, many would have insisted that the picture in my entry of 2 February 2011 were pornographic, while now-a-days it could appear in a children's book without fuss.) Still, the text in that entry contains the term sado-masochistic and there are pictures, and Norton's classification was probably mediated with weak AI; indeed, once other flags were thrown, the appearance of the word dominatrix in a follow-up entry may have been seen as further PoP.

Most WLANs that filter do so by way of a DNS table. When a browser seeks content located in terms of a URI or of a URL, and that specification includes a domain name, the domain name is converted to an IP number by way of a DNS table. By censoring the table that is used, the WLAN can block domains.

Some people subvert this censorship by way of a proxy server, which is no more than some site that will act as an intermediary; fetching content from the blocked domain. The obvious problem here is that the proxy may be identified and blocked as well.

A better subversion is to use a different table than whatever is being supplied by the WLAN. In particular, one may configure one's system to use DNS tables provided by Google, or perhaps by some other third party. But be alert that using an alternative DNS table may not be a good idea in other contexts. (For example, when using a subscription ISP that places quotas on content for most sites, but with exceptions.)

[1]The words cunnilinctus and cunnilingus are synonymous in English and in some other languages; but in Latin cunnilinctus referred to the act, while cunnilingus referred to a performer of that act. The latter word acquired its more recent meaning as a result of incompetent posturing (something that has figured more than once in attempts to borrow foreign terms and phrases). Efforts to clean-up this particular mess have repeatedly failed, but I avoid participating in it, by using the word that is both proper English and proper Latin. Hence my use of the less common term.
