## Why this rule exists

Filter evasion escalates a campaign from being filtered to being enforced against, because it demonstrates intent rather than error. It is also self-defeating: a consumer whose opt-out does not register complains to the carrier instead.

## How to fix it

Remove any deliberate misspelling, character substitution, or spacing trick. Write plainly and let the content stand on its own.
