Nominet now filtering .uk domain registrations for ‘sex-crime content’
Amazing. Massive nanny-stateism of the ‘something must be done’ variety, with a 100% false-alarm hit rate, and it’s now policy.
‘Nominet have made a decision, based on a report by Lord Macdonald QC, that recommends that they check any domain registration that signals sex crime content or is in itself a sex crime. This is screening of domains within 48 hours of registration, and de-registration. The report says that such domains should be reported to the police.’ [….] ‘The report itself states […] that in 2013 Nominet checked domains for key words used by the IWF, and as a result reported tens of thousands of domains to IWF for checking, all of which were false positives. Not one was, in fact, related to child sex abuse.’
