If your account has been penalized (sanctioned), you can view the details via the following paths:
- Notifications → System message → More button → Penalty history page
- Settings → My Account → Account details → Penalty history → Penalty history page
You can use the above paths to see if your account has been sanctioned, the length of the sanction, and a detailed penalty report. If you believe your punishment details are unfair, you can appeal.
