As Twitter now have a UK office, I thought I would see what data they hold about me. Thanks to the UK's Data Protection act, it's really simple to request the information.
I wasn't expecting a whole CD's worth of information - like Facebook provides users - but what I did get surprised me.
Twitter UK has no control or responsibility over the user information in the Twitter service and cannot respond to these sorts of requests.
So, I was rather surprised to see Privacy International telling people to contact Twitter's UK office.
I'm not sure whether PI are mistaken, or Twitter UK are.
