SentinelBot

SentinelBot is a security-focused Discord bot designed to help server administrators protect their communities. It provides automated monitoring and response features against spam, raids, phishing links, and suspicious accounts. It also includes emergency controls and a backup and restore system for server configuration.

Main features:

Policy management Administrators can view and configure server security policies. This includes setting minimum account age requirements, raid detection thresholds, spam and mention limits, link filtering, and a whitelist for roles that are allowed to use @everyone or @here.

Join watch The bot automatically checks new members, enforcing account age restrictions and detecting potential raid activity when many accounts join within a short period. It logs suspicious activity and can notify the user via direct message.

Message watch The bot enforces limits on how many messages a user can send within 10 seconds, prevents excessive mentions or mention bombs, blocks abuse of @everyone and @here (unless the sender has a whitelisted role), and filters suspicious phishing links. Official Discord Nitro gift links are allowed, but fake ones and common scam domains are blocked.

Admin controls The bot provides panic and lockdown commands. Panic makes all text channels read-only in emergencies, while unpanic restores permissions. Lockdown can block newly created or newly joined accounts if they fall below thresholds set by the administrator.

Backup and restore Administrators can create backups of server roles, categories, channels, and permissions. These backups can be listed, deleted, and restored in a non-destructive way. This allows quick recovery from accidental changes or server raids.

In short, SentinelBot helps Discord server owners keep their communities safe by combining preventive policies, automatic enforcement, and recovery tools in one reliable bot. It is designed to run continuously and scale to hundreds of servers with minimal resource usage.
