Tumblr is classified as preview. Use Centinel to monitor its behavior and decide whether to allow, block, challenge, or monetize its access to your content.

Centinel automatically detects Tumblr using behavioral fingerprinting. When detected, you can allow it, block it, challenge it with an interstitial page, or set a per-request licensing fee — all enforced in real-time with under 2ms latency.
