Old blocked account

When I was younger, I made an account and used it for every account/profile on the internet. Now I want to change a few things, but i can't because my account is blocked because of privacy reasons. I tried using the Account Verification, but i don't know much of the account anymore. It is like 4 years ago, that I used it for emails and contacting people. So i can't fill the questions in genteel.

So please any help, I need the account for games and social network sites.

Is there like an other account verification or something else to get my account back running ?

Thanks
