Jeff Vinall, a Conservative Party activist who is director of communications for the Oxford University Tories and is a second year law student at Brasenose College has abused the US Digital Millennium Copyright Act to censor a website that reproduced a posting from his Facebook account in which he called Nelson Mandela a "terrorist," shortly after Mandela's death.
Vinall sent a DMCA takedown notice to the hosts of the UK-based website Political Scrapbook after an initial demand to censor their reporting was declined. The DMCA is an American statute and notices issued under it have no standing in the United Kingdom; furthermore, it's clear that the brief quotation from Vinall qualifies as fair use under the American copyright law and fair dealing under English and Welsh copyright law.
In my opinion, Vinall is trying to have his cake and eat it too. I think he believes that Nelson Mandela was a terrorist, but he also believes that saying this aloud brings him and the party into disrepute. At the same time, I think he believes that repudiating his tasteless remarks will alienate a sizable number of Conservative supporters who also hated Mandela and cheered his death -- so using bullying, censorious tactics to suppress the reporting of his remarks is way for him to suppress news of the remarks without having to issue an insincere apology through gritted teeth that would disgust the party's reactionary wing.
