Yes. A free server can block 100 words and 50 sites, and Premium raises those to 400 and 200.

Will it punish my moderators?

No. Anyone who can manage messages is skipped by default, and you can exempt more roles and channels.

How does it stop raids?

The account age gate turns away accounts younger than the number of days you pick. Raids are nearly always accounts made minutes earlier.

Nine rules that act on messages the moment they're sent, without waiting for a moderator. Each rule has its own response, from a delete to a ban.

An account age gate turns away brand new accounts before they say a word, which stops most raids.

Banned words, invites, links, mass mentions, floods, repeats, caps, emoji spam and walls of text
Five responses: delete, warn, timeout, kick or ban
Whole-word matching, so a short banned word doesn't catch longer ones
A safety limit on automatic kicks and bans per hour
Roles and channels you exempt are skipped

Open the dashboard, find Automod, and switch on the rules you want. Each one has its own response and its own thresholds. Nothing is on until you turn it on.
From Discord, /automod rule switches one on or off and /automod status shows what is running.
Set the exemptions before you switch anything on. Anyone who can manage messages is skipped by default, and you can add roles and channels on top.
