The best defence against being forced to surrender information is not to store or process it in the first place.

The small number of overall data requests – Wikimedia also said that it handed over information in just 14 percent of the 56 cases – stems from the limited amount of information that Wikipedia holds on the almost 22 million users who edit the website’s content.

Typically, Wikipedia stores only basic information like a computer’s Internet protocol, or I.P., address, a digital signature that gives a user’s location, and email addresses. The website also does not hold onto the data for more than 90 days.
