Configure security, CAPTCHA, geography, and entry limits

Reduce automated and ineligible activity while keeping legitimate participation usable.

Open Security and configure the controls available to the product: CAPTCHA, repeat-entry limits, geography, age or eligibility gates, email or phone verification, and other request protections.

Match every enforced limit to the official rules. Test allowed and blocked attempts without weakening production settings. Security signals reduce abuse but do not replace winner eligibility review or documented moderation.

Use the least intrusive control that addresses the actual risk. Overly aggressive restrictions can block shared households, corporate networks, travelers, or people using privacy tools.
