MetaCert: .XXX Domains Account for Just 0.56% Of Porn Less Than .info & .Org

Posted on the 12 December 2012 by Worldwide @thedomains

According to a new analysis by MetaCert, a San Fransisco web-blocking firm, Porn is still largely found on .com domain names with .xxx domains ranking only 6th in terms of TLD’s containing the most porn, even behind .org and .info.

In the story carried in the guardian.co.uk,  MetaCert found that the .XXX extension accounted for just 0.56% of porn sites.

.Com, .net, and .org domains contain 83.32%, 8.13% and 0.9% of the relevant domains respectively, adding up to 92.35% of the total that it blocks.

MetaCert which is based on San Fransisco as been researching and developing its crawling and classification platform for the past six years, and has just spent 12 months tweaking the crawler-based algorithms to construct the world’s largest database of pornography web sites.


Paul Walsh, chief executive of MetaCert is quoted in the article as saying:

Every day we are given a list of .xxx domains that are registered”

“Given that the number of .xxx domains represents 0.56% of our data set and they have been on sale for a year – it’s coming up to the anniversary this week – I would say that new TLDs will not pose any issues.”

MetaCert, based in San Francisco, found that there are approximately 5,000 URLs per pornography website, and that on average each site links to another 10 sites.

According to MetaCert, which has developed a web-filtering technology, a scan of 645 million web pages – out of 3 billion or so online – contains more than 31 billion links to porn.

Here is where the porn is according to to Meta Cert by TLD:

“Every day we are given a list of .xxx domains that are registered,” Paul Walsh, chief executive of MetaCert, explained to the Guardian.

“We upload the domains to our system and they are then automatically labeled and crawled. All other sites/TLDs to which they link and also contain porn, are then labeled and crawled for more sites.”

And porn sites turn out to be surprisingly interconnected:

The location of porn sites is also heavily focused in the US, with 58.9% located in there. The Netherlands is the next largest, with 27%, followed by the UK (7.4%) and Germany (1.5%) …
