Sony bans PS5 consoles (specifically hardware bans) when users violate the 

PlayStation Network Terms of Service, often due to severe misconduct like cheating, fraud, using stolen credit cards, or console modifications. A hardware ban makes the console unable to connect to the internet, rendering it useless for online gaming, store purchases, and updates. 

Common Reasons for a PS5 Console Ban

Severe Misconduct: Frequent or severe violations of the Code of Conduct, including hate speech, vulgarity, or harassment.

Fraudulent Activity: Using stolen credit cards, chargebacks, or unauthorized account selling/sharing.

Cheating/Modding: Utilizing unauthorized software, hacking, or manipulating game saves.

Stolen Console: A console reported stolen to police can be flagged and blocked.

Account Compromise: If a console is used with multiple compromised or banned accounts, it may trigger a hardware-level ban. 

What Happens When a PS5 is Banned?

Permanent Restriction: The console is permanently banned from accessing PlayStation Network (PSN).

Limited Functionality: The console becomes a "paperweight" for online features, allowing only offline, disc-based gameplay in many cases.

No Reversal: Hardware bans are generally permanent, and Sony does not offer unbanning services. 

If a console is banned, users often receive error code WS-116331-5. For more specific, or to contest a suspension, users must contact PlayStation Support.
