Re: People will forget...
I did an experiment 5 years ago, creating, using and then deleting accounts, and them coming after 3 months to try and find my online presence.
Facebook didn't delete what they knew about me, only my public facing account. Apple didn't either. Yahoo, Google and Microsoft (surprisingly) all did as asked.
Even now, 5 years later, that deleted Facebook account and it's friends data is still around, associated to my IP address. I don't have a Facebook account, they are data scumbags, but creating a fake account from my IP address, with no real info, still suggests my mum and my work colleagues as friend suggestions. Stored data about friends and IP addresses is the only way this could happen.
