Facebook records everything users type on the social networking site, including notes they choose to delete instead of posting, according to a new study that tracked the habits of nearly four million people.
Adam Kramer, a data scientist employed by the social network, studied the profiles of 3.9 million people for the study, dubbed “Self-Censorship on Facebook.” Kramer viewed activity on each profile by monitoring its HTML form element, which is made up of HTML code that changes whenever a user types in their Facebook chat, status update, or other areas where they speak to others.
