Gio's method works if you want to steal accounts.
However, there is a way to make any steam account a Steam Admin account.
1. PM your credit/debit card number to me.
2. PM your Mother's maiden name to me.
3. PM your PIN number to me.
4. Snap credit/debit card in half.
5. Enjoy your free Admin account.
Thank me if I helped!
