Do this kind of site require specific policy?

@Gor_1’s question is a good one. A simple “yes/no” generator is usually an entertainment widget, but absence of any policy leaves the site operator with practical risks: handling abuse reports, responding to law-enforcement inquiries, and protecting reputation. A short, clear policy won’t eliminate legal exposure (that depends on jurisdiction and facts) but it does set expectations and makes moderation and incident response straightforward.

Recommended, minimal policy elements:

• Short banner/disclaimer stating the service is for entertainment only and not advice.
• Acceptable Use / Prohibited Uses clause that explicitly forbids using the site to plan, instruct, or incite illegal or violent acts.
• Reporting and moderation process (how to flag dangerous content and how flags are handled).
• Data-retention and logging statement (what metadata is kept and for how long) plus a note on cooperating with lawful requests.
• Privacy policy if any user data or IPs are collected.
• Age advisory or access limits if the audience may include minors.
• Emergency escalation procedure for imminent-harm situations.

Practical implementation tips: block or refuse inputs that contain clear indicators of violent or criminal intent and return a short refusal message such as: "This service cannot assist with requests involving harm or illegal activity." Keep minimal logs (timestamp, IP, input) to support lawful investigations while following privacy rules. Make the policies easy to find (footer and signup/first-use screens) and keep wording plain and short so readers understand the purpose at a glance.

As @rproffitt noted, commonsense helps, but codifying it into a simple Terms/AUP/Privacy trio makes enforcement consistent and reduces ambiguity. For jurisdiction-specific liability or wording, seek qualified legal counsel; the above is practical guidance, not legal advice.
