Do NOT multi-stream when: the primary platform's contract requires exclusivity (Twitch Partner agreements include exclusivity clauses for live broadcasts, and some Kick or YouTube creator deals do as well), the platforms have incompatible content policies (broadcasting adult content alongside SFW platforms violates SFW platform terms), or the production overhead exceeds the incremental audience benefit.

The exclusivity check is the most common reason to skip multi-streaming. Read the small print of your platform agreements. A Twitch Partner who multi-streams to YouTube Live during the exclusivity window risks losing Partner status and the associated revenue benefits. The exclusivity costs more than the multi-stream gains.

The content policy check is structural. Multi-streaming an adult broadcast to a SFW platform is a fast path to platform suspension on the SFW side. Even multi-streaming a borderline broadcast (mature language, suggestive content) to platforms with different tolerance levels can trigger strikes on the stricter platform.

The production overhead check is judgment. If multi-streaming is doubling your prep time without doubling your incremental audience, single-platform focus produces a better result.
