# Custom blocklist

Phrases your mods add in /settings. Sift matches whole words and sees through spaced-out and leetspeak spellings.

The blocklist is for words you want gone right away, no smart check needed. Sift matches whole words, not bits hiding inside other words. So blocking a short word won't wreck innocent messages the way a naive filter does.

## How matching works

-   Plain phrases match whole words. Blocking cat leaves category and concat alone.
-   The same check runs on cleaned-up text too, so c a t, c@t and the usual leetspeak spellings still hit.
-   Wildcards: scam\* matches scammer, \*coin matches fakecoin, and fr\*e matches fr3e and fr!e. A \* in the middle stands for a symbol or digit, not letters, so add the plain word too if you want every spelling.
-   Multi-word phrases match in order, with spaces between the words.

## What happens

A hit deletes the message, adds strike points, logs a case and DMs the member the reason. On a Sift Max network, the linked servers' blocklists merge into one.

## Allowlist interaction

Allowlisted phrases get cut out before the other checks run, so a gaming term you've vouched for stops setting things off. Everything left in the message still gets checked. Allowlisting one word won't hide a real problem sitting in the same sentence.
