How fast do signals propagate through reputation models?

Signal propagation speed varies by provider and signal type, but most engagement data feeds into reputation models within hours to days. Major providers process billions of messages daily with near-real-time feedback systems.

Negative signals typically propagate faster than positive ones. Spam complaints and spamtrap hits can affect reputation within hours because providers prioritize protecting users from ongoing abuse.

Positive signals accumulate more gradually. Building trust requires consistent positive behavior over weeks, while losing trust can happen in a single bad campaign.

Reputation models are like harbor authorities who hear about smuggling incidents immediately but take time to recognize consistently honest captains. Bad news travels fast. Good news requires sustained evidence.
