You mentioned that they got rid of a lot of profile information ( for all we know, that person might simply be interested in having you Memento'ed ) (ie) Just delete all you stuff ( mails , foursquare checkins , instagram pics , facebook posts , last.fm scrobbles , open table reservations , evernote saved articles , pocket saved articles ).

This is not just a loss of your netflix password . It probably leaked a ton of information about you , your password pattern ! I bet you have the same password for atleast a few more services. You have to protect them .
