1. Why do you think deleting and creating a new account helps? The data isn't account-bound, it's aggregate.

It's funny, your post feels pretty representative of what I've come to realize is "privacy extremism". In the name of privacy, refusing to tolerate or even understand what websites, companies etc are doing. It's counterproductive to your own cause. I mean, even if you thought you were doing yourself a favour deleting your own accounts, you're a fool if you think it's not possible to associate your old accounts to your new ones.
Once the trolls there start stalking you simply for making comments, you'll understand.
