How do I Удалить my account???

Do the following:
1. Do something to someone so they'll Сообщить you
2. If you're making another account, which I seriously doubt, Удалить your email adress from this account or
3. Ask someone to Сообщить you

Do something bad and get banned.

There is no way to Удалить your account besides getting it suspended.

Just change your email and Пароль and completely forget about it.
