Flood & raid filter
Raid spam is not one message — it is a burst. ModShield watches channel spread, message rate, and identical content together, then removes the whole burst instead of fighting message-by-message.
- Sliding window per user
- Burst / spread / duplicate signals
- Bulk cleanup when possible
- Trip memory across restarts
Why teams turn it on
One window, three signals
Trip on how wide the spam spreads, how fast it lands, or whether the same content is pasted everywhere — classic floods and coordinated paste raids in one policy.
Bulk cleanup
Where the platform allows it, the burst is cleared in one bulk delete instead of a hundred round-trips that lose the race to the next paste.
Memory across restarts
Optional trip memory means a bot restart does not forgive an active raider mid-attack.
Scoped to what hurts
Watch all messages, attachments, or links only — so image dumps and link storms can be treated differently from normal chat.
How it works
1. Watch the window
Each user is scored inside a sliding time window: message count, how many channels they hit, and optional identical-content repeats.
2. Trip the policy
When a threshold trips, ModShield treats the recent burst as one incident — not eight separate “oops” events.
3. Clean and escalate
Bulk delete where possible, then apply your shared strike / jail / timeout policy so flood handling matches the rest of moderation.
Real situations
Emoji / sticker storms
A user fills five channels in ten seconds. Spread + rate trip together even if no single message looks “bad”.
Copy-paste raid
Identical scam text lands across channels. Identical-content mode collapses the pattern into one cleanup.
Attachment dump
Scope to attachments so image floods are caught without punishing normal conversation pace.
FAQ
Will fast typers get punished?
Thresholds are yours. Set them for raid scale, exempt staff/bots, and tune until normal chat stays quiet.
Does it replace raid join protection?
No. Flood filter is message-side. Pair it with Raid protection for join waves at the door.
