# Filter evasion

Spaced-out letters, lookalike characters, and words split across messages. Sift stitches them back together before scoring.

Before the smart check runs, Sift cleans up the text: leetspeak, stretched-out letters, s p a c e d words. It can also join recent messages when a line looks like the next piece of a banned phrase split across posts.

## Split messages

Spread a blocked word over two or three quick messages and the chain logic scores the joined text, then acts on the whole burst. Normal fast replies in a real conversation are less likely to chain.

## Names and threads

Nicknames, display names and thread titles go through the blocklist and offensive-term checks too. It's not just channel messages.
