Facebook Comment Picker
Pick random winners from your Facebook Page post comments with SHA-256 cryptographic proof. Filter friend tags, keywords, and entry limits automatically using the official Facebook Graph API.
How the Facebook Comment Picker Works
Run an audit-proof Facebook giveaway in 4 simple steps
Connect Your Page
Link your managed Facebook Page via official Meta OAuth. We only request read-only permissions to load your public posts and comments.
Select Post & Set Rules
Choose your giveaway post. Configure winner count (1–100), friend tagging rules (0–10 tags), page like requirements, and optional keyword filters.
Automatic API Fetching
Our system retrieves all comments directly through the Graph API, removes invalid entries, and enforces your eligibility rules automatically.
Cryptographic Draw & Proof
Winners are selected using our pre-committed SHA-256 algorithm. A public verification certificate is generated for complete transparency.
Configurable Facebook Giveaway Rules

Provably Fair Selection with Cryptographic Verification
Never worry about accusations of favoritism or rigged Facebook contests again. Fair Giveaways uses cryptographic seed commitment to guarantee integrity:
- 1. Seed Hash Commitment: Before entries close, our server generates a secret seed and publishes its SHA-256 hash publicly. This fixes the winner selection formula in advance.
- 2. Deterministic Draw: The winner is determined deterministically by combining the revealed seed with participant entries.
- 3. Independent Verification Tool: Entrants can open our Independent Verification Tool, paste the giveaway ID, and verify the draw calculation locally.

Facebook Contest Rules & Best Practices
Ensure your Facebook giveaway complies with Meta Page Guidelines
Key Facebook Promotion Policies
- Mandatory Release: Facebook requires every contest post to include a complete release of Facebook by each entrant and acknowledgment that the promotion is in no way sponsored, endorsed, administered by, or associated with Facebook.
- Permitted Entry Mechanics: You can ask users to comment on your post, mention friends in comments, like the post, or answer trivia questions.
- Prohibited Tagging Rules: Meta prohibits requiring users to tag themselves or friends in photos that they do not actually appear in. Mentioning friends in comments, however, is fully compliant.
- Facebook Page Required: Contests must be administered on Pages, Groups, or Events, not personal profile timelines.
Frequently Asked Questions
Common questions about running Facebook Page comment giveaways
How does the Facebook comment picker work?
Connect your Facebook account via secure Meta OAuth, select the Facebook Page and post you want to run a giveaway on, set entry rules (friend tags, page like requirement, keywords, number of winners), and set an end date. Our system fetches all comments directly through the official Facebook Graph API, applies your filters, and selects winners using a provably fair cryptographic algorithm.
Do I need a Facebook Page, or does it work on personal profiles?
You must have admin or management access to a Facebook Page. Due to Meta's strict platform privacy policies and Graph API constraints, automated comment retrieval is only permitted for Facebook Page posts. Third-party applications cannot read comments on personal profile timelines or private groups.
Is the Facebook comment picker free to use?
Yes! Fair Giveaways offers a generous free tier supporting up to 500 comments per giveaway, complete with friend tagging filters and provably fair cryptographic proof. For larger community campaigns, you can purchase single giveaway passes or subscribe to monthly plans for up to 6,000 comments, keyword filtering, and CSV export.
Can I verify that the Facebook giveaway winner was picked fairly?
Absolutely. Every giveaway uses a committed cryptographic seed (SHA-256) published before entries close. After the winner is drawn, the secret seed is revealed. Anyone can enter the giveaway ID into our browser-based Independent Verification Tool to re-run the algorithm locally and confirm the outcome was mathematically unbiased.
Can I pick multiple winners from a single Facebook post?
Yes. You can select anywhere from 1 to 100 winners in a single draw. Each winner is drawn independently using our provably fair PRNG algorithm with equal probability.
Can I require participants to tag friends in their comment?
Yes. You can specify a minimum friend tag requirement between 0 and 10 tags. Comments that do not include the required number of @mentions are automatically filtered out.
Can I filter comments by keyword or phrase?
Yes. On the Creator and Pro plans, you can set a required comment keyword (e.g., '#giveaway' or a specific contest answer). Any comment lacking the exact keyword is excluded from the draw.
Does Fair Giveaways require my Facebook password?
Never. Login and permission authorization occur entirely through Facebook's official OAuth window. Fair Giveaways only requests the minimum read permissions needed to fetch your Page posts and comments. We never see or store your Facebook password.
