How to Prevent Discord Raids and Spam Attacks: Complete Server Security Guide

Discord raids and spam attacks are among the most common threats faced by public servers. A raid usually occurs when multiple accounts join a server at the same time and flood channels with spam, scam links, excessive mentions, or offensive content. Fortunately, Discord provides several built-in moderation tools that can significantly reduce the risk of raids and automated spam attacks.

A strong defense combines verification levels, AutoMod rules, slowmode, role permissions, and emergency moderation procedures.

Enable Discord Verification Levels

Verification levels are the first line of defense against raids. Requiring users to verify their email address, account age, or phone number prevents many fake and newly created accounts from sending messages immediately after joining.

For most public servers, High verification is recommended because it requires users to have a verified email address, an account older than five minutes, and at least ten minutes of server membership before they can interact.

Configure Discord AutoMod

Discord AutoMod can automatically block spam, scam links, offensive language, and excessive mentions before messages appear in public channels.

Recommended AutoMod rules include:

• Keyword filters for scam phrases and phishing links
• Spam detection
• Mention limits to stop mass ping attacks
• Moderator alerts when a rule is triggered

AutoMod should be enabled on every public server because it reduces moderator workload during active raid attempts.

Use Slowmode During High Activity

Slowmode limits how frequently members can send messages in a channel. During a raid or spam wave, enabling slowmode can immediately reduce flooding and make moderation much easier.

A delay of 5-15 seconds is often enough to stop automated spam bots while allowing normal conversation to continue.

Restrict Role Permissions

New members should not receive powerful permissions immediately after joining.

Create a New Member role with limited permissions, such as:

• No @everyone mentions
• No invite creation
• No webhook management
• No channel management
• No role management

Trusted members can receive additional permissions after verification or manual review.

Emergency Moderation During a Raid

If a raid is already happening, take immediate action:

• Increase the verification level.
• Enable slowmode on active channels.
• Lock vulnerable channels temporarily.
• Remove suspicious accounts.
• Disable invite links if necessary.
• Notify moderators through a private staff channel.

Having a predefined emergency moderation plan allows moderators to respond quickly without confusion.

Best Security Setup

For most public Discord communities, the recommended configuration is:

• Verification Level: High
• AutoMod: Enabled
• Mention Limit: 5 mentions
• Slowmode: Enabled during spikes
• New Member Role: Restricted permissions
• Moderator Team: Active during large events

Conclusion

Preventing Discord raids requires multiple layers of protection rather than a single moderation tool. Verification levels stop many fake accounts before they can participate, AutoMod blocks spam automatically, slowmode reduces message flooding, and role permissions limit what new members can do. Together, these features provide a strong defense against raids and spam attacks while keeping your Discord community safe and organized.
