I did this once 10 years ago. I had gone through the process of deleting my old account, actual deleting and not just deactivating. I then logged onto the account that had been "deleted" years earlier.
They will never delete the data you've given them. The database they collected on everyone is too valuable. The only thing you can do is create misinformation and hopefully most of the data becomes useless.
This was an old troll or sock account I made. I used to play mafiawars on a site called tagged and then zynga sold the game to fb so everyone in the clan moved over there. I had about five fb accounts to build my main mafiawars account with. When I logged on to this account it had no friends. I lost access to my other accounts and this is the only one I found log in details to.
