KarmaGate
Anti-brigade & cross-subreddit karma gating — screen every post and comment before it goes live.
Why you need KarmaGate
Brigading is organized, invisible to AutoMod, and expensive to clean up after the fact.
Brigading is organized
Off-site communities and hostile subreddits coordinate raids that flood your subreddit with bad-faith content.
AutoMod can't see it
AutoMod only checks account age and karma in your subreddit — it has no view of an account's history elsewhere.
Cleanup is after-the-fact
Mods spend hours removing damage that's already gone viral. KarmaGate acts before it's live.
What KarmaGate does
Six advantages that keep bad-faith content out of your community.
Pre-publish screening
Every post and comment is checked the moment it's submitted.
Weighted risk score
Participation in hostile subreddits is weighted into a brigade-risk score.
Severity ladder
Filter → remove → report → temp-ban, applied automatically.
Transparency & appeals
Authors are told why content was held, and can appeal by replying.
Mod-alerts
Discord or Slack webhook alerts for high-severity actions.
Shared blacklist
Opt into a curated starter blacklist shared across installs.
KarmaGate vs AutoMod
The difference is what you can see — and when you act.
AutoMod (native)
On-subreddit karma and age only. Rule-based, reactive, and blind to an account's history elsewhere on Reddit.
KarmaGate
Cross-subreddit history, weighted scoring, and pre-publish enforcement — proactive, not reactive.
How it works
A weighted score maps to an automated action.
Under threshold
Content stays up — the author has no meaningful match.
Threshold → 2×
Filtered to the mod queue for review (not spam).
2× → 3×
Removed as spam and reported for review.
3× and above
Removed, reported, and the author is temp-banned.
How to use it
Three steps to a cleaner community.
Install
Install KarmaGate to a subreddit you moderate and approve its mod permissions.
Configure
Set your blacklist, weights, threshold, and action policy in the settings form.
Relax
KarmaGate screens every submission and handles enforcement — with appeals built in.
Help & FAQ
Common questions, answered.
Why was a post held?
The author's global history matched your blacklist and crossed the threshold. They get a modmail note explaining why.
How do I reduce false positives?
Raise the threshold, lower a subreddit's weight, or whitelist trusted users.
How do appeals work?
Authors reply to the notice to appeal. KarmaGate re-scores them and auto-restores if below threshold.
Can I get alerts?
Yes — connect a Discord or Slack webhook for high-severity actions.
