# Floods, repeats, and mass mentions

Rate limits and pattern rules for fast posting, copy-paste repeats, @everyone spam, and one post blasted across channels.

These rules don't care what a message means. They're here for volume: floods and raid-style noise. You can tune every threshold in /settings.

## Message flood

Sift spots floods from timing. Rapid chains, short bursts, a high send rate that just keeps going. There's no fixed "5 messages in 6 seconds" rule. Edits count too, so editing one message over and over won't get around it.

## Duplicate spam

Posting the same text, or nearly the same, again and again in one channel counts as spam.

## Mass mentions

Messages that ping a big pile of users or roles at once get blocked.

## Cross-channel spam

Paste the same link or line into several channels in a short window and it's flagged as cross-channel spam.

## Lorem mode

With lorem mode on, some spam still gets deleted outright instead of swapped for placeholder text. A fake paragraph would only add more clutter.
