These go straight to a permanent ban, per https://nabzclan.vip/threads/46/:

• Scams, phishing, malware, or selling or trading accounts.
• Sexual content involving minors. This is also reported to the authorities.
• Doxxing or credible threats against a person.
• Posting leaked or stolen certificates, keys or paid-app files after being told not to.
• Evading a ban with a new account.
• Mass spam or a coordinated raid.

Duplicate accounts are closed and, depending on what they were used for, can lead to a ban on the main account. Evasion after a ban is a permanent ban.

If you think a ban was a mistake, see "How do I appeal a ban or warning?". Do not make a new account to appeal; that counts as evasion.
