## Why this rule exists

Cold agency pitching to businesses scraped from directories is unsolicited commercial messaging with no consent behind it, and it is one of the most frequently reported patterns on the network. Messaging clients who engaged you is entirely different.

## How to fix it

Cold B2B prospecting by SMS cannot be registered — the recipients never consented. Restrict messaging to clients who opted in with you directly.
