This is most disturbing. I remember big change in facebook policy on 1.1. 2015 that would mean that deleting your account would not delete data they had on you. Up to that point their policy was that after you delete, data about you is erased (at least in europe).

I did delete the account before that date with few other people (mostly because of that policy coming).

I never tried coming back but if they still kept all the data, that is pretty substantional. One could sue facebook for that or am i missimg something?
