Anti-Spam System

Sentinel Bot's Anti-Spam system protects your server against spam messages, unauthorized links, and annoying behavior automatically. It detects and blocks spam in real-time, keeping your server clean and safe.

You can manage all Anti-Spam protection from Discord commands (/antispam) or from the web panel in the Settings → Anti-Spam tab.

What does Anti-Spam detect?

The Anti-Spam system automatically detects and blocks:

• ✅ Repeated Messages: Users sending the same message multiple times
• ✅ Repeated Words: Messages with the same word repeated many times
• ✅ Excessive Mentions: Too many mentions of users or roles in a message
• ✅ @everyone/@here: Mass mentions (blockable)
• ✅ Excessive Links: Too many links in a single message
• ✅ Repeated Characters: Messages with repeated characters (e.g., "aaaaaaaaa")
• ✅ Unauthorized Links: Advanced protection against unauthorized links

Configuration

Enable/Disable

Using commands

• /antispam enable - Activates all Anti-Spam protection
• /antispam disable - Deactivates all Anti-Spam protection
• /antispam status - View complete protection status

Using the web panel

1. Go to your server in the web panel
2. Settings tab → Anti-Spam
3. Find "📢 Anti-Spam Protection"
4. Activate or deactivate the "System Status" switch

Configure Action

When spam is detected, you can choose what action to take:

• ⚠️ Warn: Sends a private warning message to the user
• 👢 Kick: Kicks the user from the server
• 🔨 Ban: Permanently bans the user

Recommendation For new servers, use "Warn" first. Once you see what type of spam you receive, you can adjust the action.

Repeated Messages Threshold

Define how many repeated messages trigger protection.

Example If you configure 5 messages, the bot will delete all repeated messages when a user sends the same message 5 times in a minute.

Maximum Mentions per Message

Limits how many users/roles can be mentioned in a single message.

• 0: Blocks all mentions (not recommended)
• 1-3: Very strict, only individual mentions
• 3-5: Moderate, allows normal mentions
• 5+: Permissive, allows many mentions

Allow @everyone/@here

Controls whether users can mention @everyone or @here.

Link Protection

One of the most powerful features of Anti-Spam is advanced link protection. You can block all links except those you explicitly allow.

How does it work?

1. The bot detects all links in messages
2. Checks if the user is on the whitelist (if they are, they can send any link)
3. Compares the link with your whitelist of allowed domains
4. If the link is not allowed, deletes the message and executes the configured action

Configure Link Protection

discord.gg
youtube.com
github.com
twitch.tv

Whitelist Rules

• ✅ You can put just the domain (e.g., discord.gg)
• ✅ You can put the full URL (e.g., https://discord.gg)
• ✅ The bot automatically normalizes (ignores www, protocols, etc.)
• ✅ Subdomains are included (if you allow discord.gg, status.discord.gg is also allowed)

Whitelist Exemption

🎫 Links in Sentinel Tickets

A special feature of the Anti-Spam system is the ability to allow or block links specifically in Sentinel tickets.

/antispam links-tickets permitir:true

/antispam links-tickets permitir:false

🚨 Specific Detections

1. Duplicate Messages

The bot detects when a user sends the same message multiple times in a minute.

2. Repeated Words

Detects messages with the same word repeated many times.

3. Excessive Mentions

Blocks messages with too many mentions of users or roles.

4. Excessive Links

Detects messages with too many links.

🎯 Best Practices

1. Start with soft actions Use "Warn" first and adjust based on what you see.
2. Adjust thresholds according to your server Large servers need higher thresholds.
3. Use whitelist strategically Add trusted users to avoid false positives.
4. Review logs regularly It will help you adjust the configuration.
5. Configure link protection carefully Add the domains you really need to allow.

❓ Frequently Asked Questions

Does Anti-Spam affect whitelisted users?

No. Users on the whitelist are exempt from all spam protections EXCEPT @everyone/@here mentions (if blocked for everyone). Additionally, they can send any link regardless of the whitelist.

What happens if a legitimate user sends many messages?

The bot only detects repeated messages (same text). If a user sends different messages quickly, it won't be considered spam.

Can I disable only link protection?

Yes. You can enable general Anti-Spam but specifically disable link protection. They are independent configurations. You can use /antispam links activar:false to disable only link protection.

How do I know if a link will be blocked?

If the link's domain is not on your whitelist AND the user is not on whitelist, the link will be blocked. However, if the message is in a Sentinel ticket and you have the "Links in Tickets" option enabled, the link will be allowed.

Are links in embeds also blocked?

The bot detects links in the message content. Links in embeds may not be detected depending on how they're sent.

Can I allow links in tickets but block them in other channels?

Yes, absolutely. That's exactly the "Links in Tickets" feature. Activate link protection normally and then enable the "Links in Tickets" option from the web panel or with /antispam links-tickets permitir:true. This way, links will be blocked in the server but allowed in support tickets.

What happens if I disable Anti-Spam protection but leave link protection enabled?

Link protection is independent. You can have general Anti-Spam disabled but link protection enabled. In this case, only unauthorized links will be blocked, but other types of spam won't be detected.
