How to Stop Spam in Discord
Why Discord spam happens, what Discord's own tools miss, and how to stop it automatically with Airwavy's Anti-Scam detection and AI Moderation.
Quick answer
Discord spam is best stopped by combining automatic detection — which removes it before members see it — with manual tools for repeat offenders. Airwavy's Anti-Scam feature runs message, URL, and behaviour detection for free on every server; Server Premium adds AI image-scam detection and a second-opinion AI Moderation layer for cases without a clean pattern match.
What you'll learn
- Why spam and scam waves happen on Discord, and why manual moderation alone can't keep up
- What Discord's own AutoMod does, and where it falls short
- How Anti-Scam's message, URL, and behaviour detection works, and what's free vs. Premium
- How to set it up, and when to add AI Moderation as a second layer
- Common mistakes that let spam through, or block real members
Why Discord servers get spammed
Most Discord spam isn't random — it's automated. Compromised accounts, scam bots, and coordinated campaigns post the same crypto-giveaway link, fake Nitro offer, or scam invite across many servers within minutes, often faster than a human moderator can react.
The larger or more public a server is, the more attractive it is to this kind of automation: a single working scam link can reach thousands of members before anyone reports it.
What Discord's own tools do about it
Discord ships a built-in AutoMod system that blocks messages matching keyword lists, mention-spam rules, and a small set of preset filters. It's a useful first layer, but it works on message content alone — it doesn't track patterns of behaviour across messages, doesn't inspect images, and has no way to know an account was already flagged as compromised somewhere else.
- Keyword and mention-spam filters catch obvious, static patterns
- Doesn't evaluate images, attachments, or behaviour across multiple messages
- No visibility into an account's history outside your own server
How Airwavy stops it automatically
Anti-Scam runs continuously in the background on every Airwavy server — there's no command to turn on, and nothing to wait on a human to notice. It combines three independent detectors — message content, URLs, and behaviour over a rolling observation window (60 seconds by default) — so it can catch a burst of similar messages, not just one obviously-bad one.
- Free on every server: message, URL, and behaviour detection, each independently toggleable, with a configurable block-confidence threshold (default 70).
- A confirmed match can auto-delete the message and post a staff alert to a private channel you choose.
- Server Premium adds AI image-scam detection (catches scam screenshots text filters miss) and opt-in cross-server protection — the moment one server flags a compromised account, every opted-in server in the network can act on it too.

Evidence: • message matches a known scam pattern (crypto giveaway link)
The message was deleted automatically.
Set it up in about five minutes
- Add Airwavy to your server and open the dashboard.
- Open Anti-Scam and choose a private staff channel — this is where alerts land, so pick one only staff can see.
- Leave message, URL, and behaviour detection on (all three are enabled by default) and decide whether to auto-delete matches or have staff review them first.
- Save, then watch the alert channel for the first few flags — adjust the block-confidence threshold if it's too aggressive or too lax for your community.
- If you have Server Premium, also enable AI image-scam detection and decide whether to opt into cross-server compromised-account protection.
Common mistakes
- Turning on auto-delete before reviewing a few alerts — start with staff review, then switch to auto-delete once you trust the threshold for your server.
- Pointing alerts at a channel the wrong people can see — flagged links are often still live; keep the alert channel staff-only.
- Assuming Anti-Scam covers every kind of spam — it targets scam-pattern content specifically. Off-topic flooding or harassment that isn't scam-shaped still needs a human call, or AI Moderation's broader signal set.
- Skipping AI Moderation — Anti-Scam is pattern-based; AI Moderation's 14 categories (Premium) catch cases without a clean pattern match, like ambiguous phrasing, mass mentions, or suspicious attachments, and only ever alerts or deletes, never bans.
Troubleshooting
A normal message or link keeps getting flagged
Lower the block-confidence threshold, or review the behaviour observation window if fast but legitimate activity — like a giveaway your own server is running — is triggering it.
Obvious spam isn't being caught
Confirm message, URL, and behaviour detection are all enabled, and check that the block-confidence threshold isn't set too high. Fast-moving, repeated campaigns are exactly what behaviour detection is built to catch.
I need something stronger than delete-and-alert
Pair Anti-Scam with /mod — warn or timeout repeat posters directly, and use /mod prune with its content filters (Premium) to bulk-clean a channel after an incident.
