Detect duplicate and fraudulent raffle entries in seconds using entity resolution, fuzzy matching, and behavioral analysis.
RaffleBattle combines entity resolution, fuzzy matching, and behavioral analysis to detect fraudulent and duplicate entries with 99.2% accuracy — in under 5 seconds per batch. Stop letting abusers steal spots from real customers.
Fuzzy matching across name, email, phone, address. Catches typo-variants and intentional misspellings. Not simple deduplication — real entity resolution that links “John Smith”, “J. Smith”, and “Jon Smyth” as the same person.
Timestamp clustering, IP correlation, device fingerprinting. Catches bot submissions and coordinated abuse rings. When 12 entries come from the same IP within 3 minutes — that's a pattern, not a coincidence.
Built on peer-reviewed entity resolution methods. Not regex — real NLP and graph-based clustering. Levenshtein distance, Soundex phonetic matching, Union-Find clustering, and connected component analysis.
CSV upload from any raffle system. Shopify, Typeform, Google Forms, custom — doesn't matter. Smart column auto-mapping handles 50+ header name variants automatically. No configuration required.
One person. Twelve entries. Every trick in the book. Here's what they do — and why basic deduplication misses it all.
Typo-variants, abbreviations, middle initials, first-name expansions. All point to one person. Basic dedup catches zero of these.
Gmail dot trick (all go to the same inbox), +alias trick (unlimited variations), multiple providers. One person, six “different” emails.
Same shipping address with St/Street/Ave/Avenue variations, empty apartment numbers, shared IPs, rapid-fire submissions within minutes. All the fingerprints of coordinated abuse.
Upload, scan, review, export. The entire pipeline runs in under 5 seconds.
Every entry is analyzed across eight independent detection dimensions. Even one match flags — but the real power is when multiple dimensions converge on the same entity.
Levenshtein distance + phonetic matching (Soundex). Catches John/Jon/Jonathan, typos, abbreviations, and intentional misspellings.
LEVENSHTEIN + SOUNDEXGmail dot tricks, +alias variations, domain variants, disposable email detection. Normalizes to canonical form before comparison.
NORMALIZATIONSt/Street, Ave/Avenue, unit variations, empty apartment tricks, PO box formats, transposed digits. Standardizes before matching.
STANDARDIZEFormat variations, area code analysis, country code canonicalization. Catches number rotation patterns and VoIP indicators.
CANONICALIZEShared device and network detection. When multiple entries originate from the same IP or device fingerprint, they're linked.
BEHAVIORALRapid-fire submission pattern detection. Entries clustered within seconds or minutes flag coordinated bot or manual abuse.
TEMPORALConnected component analysis linking related entries. If A matches B on email and B matches C on address, all three are grouped.
UNION-FINDEach cluster scored 0-100% match confidence. High-confidence flags auto-remove; borderline cases surface for human review.

Known challenges and how RaffleBattle addresses each one.
Risk: Legitimate entries with similar names/addresses could be wrongly flagged.
Mitigation: Confidence scoring (0-100%) lets you set thresholds. Built-in manual review UI surfaces borderline cases for human decision. Default threshold optimized for <2% false positive rate.
Risk: Fraudsters develop new tricks that bypass current detection patterns.
Mitigation: Continuous algorithm updates. Behavioral analysis catches novel patterns even without specific rules. Graph-based clustering means new tricks in one dimension are caught by correlation in others.
Risk: Different raffle platforms export CSVs with different column names and formats.
Mitigation: Smart CSV parser handles 50+ column name variants automatically. Tested against Google Forms, Typeform, Shopify, JotForm, Wufoo, and custom exports. No manual mapping needed.
Risk: Very large raffles (50K+ entries) could hit processing limits.
Mitigation: Streaming architecture handles 100K+ entries. Horizontal scaling ready. Processing is O(n log n) not O(n^2) thanks to blocking/indexing strategies before pairwise comparison.
