How to Protect a Discord Server from Raids and Spam

A raid is a coordinated join or message flood from many accounts at once. This checklist covers built-in Discord defenses, invite hygiene, and staff response. Note: anti-raid (join and flood defense) is a different problem from anti-nuke (rogue-admin destruction — see our anti-nuke explainer).

Turn on Discord AutoMod and verification

In Server Settings → Safety Setup, enable AutoMod rules for spam content, mention spam, and flagged words, with alerts to a private staff channel. Set the verification level to at least “Medium” (verified email) and consider the ten-minute wait for large public servers. These built-in gates stop most low-effort floods before your staff wakes up.

Give staff roles least privilege

Helpers need Timeout Members, Manage Messages, and Kick Members — not Administrator. Set the staff role in /settings so only that role can run moderation commands. Keep the bot role above moderator roles so timeouts and bans are not blocked by hierarchy.

Review invite links

Open Server Settings → Invites and delete links with unlimited uses or no expiry that you did not create. Create one never-expiring vanity-style invite you control, and make event invites temporary. During an active flood, pause all new invites until the wave passes.

Handle suspicious URLs without blocking legitimate links

Turn on ARK Bot anti-link rules in /settings for channels where new members post, and exempt staff and trusted-role channels so guides and resources still work. Teach members to hover before clicking and to report odd “free Nitro” or “airdrop” links to staff instead of reposting warnings publicly.

Incident response during a flood

Switch slowmode on in hit channels to slow the flood.
Timeout or ban the flooding accounts; use /clear to remove spam bursts.
Check /warnings history so repeat offenders get bans, not fifth warnings.
Post one calm announcement; avoid amplifying the attackers' handles.

Where ARK Bot anti-raid and moderation fit

ARK Bot contributes anti-link rules, a honeypot channel that catches automated posters, join-spike detection with verification gates and join lockdown while staff review, and the /warn, /warnings, /timeout, /ban, and /clear workflow for cleanup. Lockdown slows a wave; it does not replace judgment — during a large attack, still restrict invites manually, keep extra staff online, and review each locked-down account before letting it back in.

After a raid

Review which invite or post the accounts came from, prune it, and tighten the verification level for a few days. Thank the staff who responded, log what worked, and update this checklist while it is fresh.

Common mistakes

Leaving unlimited-use invites posted on public listing sites.
Granting new “emergency mods” Administrator in a panic.
Arguing with attackers in public instead of timing out quietly.

Conclusion

AutoMod plus tight invites prevents most floods; practiced staff with clear commands cleans up the rest. Rehearse the response steps once so the real event feels routine.
