AutoMod
Also called Discord AutoMod
Discord’s built-in content filter, which inspects messages at the platform level before delivery. It is faster than any bot, harder to evade, and free — but it only inspects content.
AutoMod handles preset filters for profanity and slurs, mention-spam limits, custom keyword rules and its own spam classifier. Because it runs before the message is delivered, nothing downstream ever sees a blocked message.
What it does not do: act on repeat offenders, keep a case history, respond to a join-rate spike, or restrain someone who already holds permissions. That gap is where a third-party bot earns its place.
Vetox layers on top of AutoMod rather than replacing it, and adds the case history, escalation and join-rate defence AutoMod has no concept of — all on the free Starter tier except Anti-Raid, which is on Basic.
