Chap asks Facebook for data on his web activity, Facebook says no, now watchdog's on the case

Facebook's refusal to hand over the data it holds on users' web activity is to be probed by the Irish Data Protection Commissioner after a complaint from a UK-based academic.

Facebook slurps information about your device, the websites you visited, apps you used and ads you've seen via Facebook business tools and plug-ins, such as the Like button, on partner sites.

"Facebook simply does not have the infrastructure capacity to store log data in Hive in a form that is indexed by user in the way that it can for production data used for the main Facebook site," Zuck's minions said.
