I don't think that anyone has the right to keep your personal info on their site if you don't want them to.. Contact their support and see if they can help you delete the account.

Hate to be the bearer of bad new but the internet is almost like LIFE itself.

There is no way you can undo the steps you've taken, the mistakes you've made and the places you've been.
Live with it but, henceforth, be cautious.

Besides, you would not want to live your life trying to coverup past mistakes.
Too stressful to even keep up with, so relax.
