We may investigate suspected violations and may request campaign details, recipient-consent proof, and remediation plans. We may throttle, suspend, or terminate accounts that violate this policy or create risk to users, recipients, or platform reputation. Depending on severity and cooperation, we may provide an opportunity to remediate before disruption. Refunds are not issued for AUP violations. Questions? Email hello@vblinden.dev.

We may update this policy from time to time. If we make material changes, we will post an updated version here and revise the "Last updated" date above. Continued use of the service after the effective date means the updated policy applies.
