 - **PRIVACY_ASKING_FOR_PII**: Attempting to obtain personal identifying information (PII) through direct questions or insinuation.
 - **PRIVACY_GIVING_PII**: Sharing or threatening to share someone's personal identifying information (PII), including but not limited to telephone numbers, email addresses, government ID numbers, social media handles, and account passwords/credentials. This category also includes attempts to direct a user off-platform to an external platform or real-world location (DUOP).
 
-The classifier expects text input with a maximum sequence length of 512 tokens. The outputs are uncalibrated scores. The recommended cutoff for pii detection is when the sum of both categories `privacy_asking_for_pii + privacy_giving_pii >= 0.26911312`, which achives the optimal F1 score on Roblox English anonymized chat. For per-category cutoffs we recommend `privacy_asking_for_pii >= 0.2` and `privacy_giving_pii >= 0.3`.
