Yes, Togan already said that level 1 accounts are deleted after nine months of inactivity. How many characters you've had doesn't make a difference because it is based on XP level, which is a character attribute rather than an account attribute.
Thank you, I just wanted to verify that. It provides the answer the original poster sought.
To delete your account without admin intervention;
1. Kill your character by A/E, Sunning, or how ever.
2. Wait 3 week then recreate
3. Become inactive before achieving level 2
4. After 9 months your account will be deleted.
