How Rep Score is built
Your RepDex score is a single, portable trust score that combines peer reviews and verified public platform history. Everything is normalized to a 0–100 scale.
Trust score
The headline score. It blends RepDex peer reviews and imported platform reputation, weighted so recent community feedback matters most.
Seller score
Reputation when you are the seller. Combines seller-side reviews and imported public feedback such as eBay feedback scores.
Buyer score
Reputation when you are the buyer. Based only on reviews where the other party rated you as the buyer.
What feeds the score
Every source produces two numbers: a quality (0–100, how good the record is) and a weight (how much that record should count). The score is the weighted average of those sources — nothing is hidden, and every weight is capped so no single platform can dominate.
RepDex reviews
Each review is a 1–5 star grade from the other side of a real trade.
weight = (verified ? 3 : 1) × 0.5^(age_days / 365)
quality = Σ(weight × grade) / Σ(weight) / 5 × 100
Reviews tied to a verified handshake count 3×, and every review's weight halves each year.
eBay feedback
Verified eBay links import feedback score and positive percentage.
quality = positive_percent
weight = min(feedback_score, 1000) / 1000 × 40
Maxes out at the weight of ~13 fresh verified reviews.
Reddit standing
Verified Reddit links contribute account age and karma as a light trust signal.
quality = 50 + 25 × min(age_years / 3, 1) + 25 × min(karma / 5000, 1)
weight = min(karma, 5000) / 5000 × 15
Capped low on purpose — karma is not trading history.
Discord
Discord publishes no public reputation data.
weight = 0
A verified Discord link proves identity and counts toward tier connections, but never moves the score on its own.
Verified by handshake
eBay and other marketplaces can prove a transaction happened. Reddit, Discord and in-person deals cannot — which is why a review from those platforms is easy to fake in either direction. A Trade Handshake closes that gap: both traders agree to the items, value and shipping terms before the deal, then both confirm it was completed before reviews unlock.
Because that record exists, a review attached to a completed handshake carries 3× the weight of a standalone review, and the completed deal is published on the Ledger for anyone to check. Standalone reviews still count — they just count less until a deal record backs them up.
Trader tiers
Your trust score measures quality. Your trader tier measures sustained reputation — reviews received, rating, verified connections, and dispute-free standing. Tiers are assigned automatically and are sticky: they never decay from inactivity, only from a confirmed dispute. The separate Authenticated badge is not a tier — it is earned once you verify at least one external account connection.
Ungraded
Default standing. No completed reviews yet.
Common
3+ completed reviews, no unresolved disputes.
Uncommon
25+ reviews, 85%+ rating, no confirmed dispute in the trailing 90 days.
Rare
100+ reviews, 90%+ rating, dispute-free for 6 months, 1 verified connection.
Super Rare
150+ reviews, 95%+ rating, dispute-free for 12 months, 2 verified connections.
Ultra Rare
500+ reviews, 98%+ rating, dispute-free for 12 months, 3 verified connections.
Legendary
1000+ reviews, 98%+ rating, same standing mechanics. Fully automated.
The formulas
Trust score
One weighted average across every source. Scores are clamped to 100 and rounded up to the nearest tenth.
Seller score
Same formula, restricted to seller-side evidence: reviews where you were the seller, plus eBay history imported as a seller account.
Buyer score
Same formula, restricted to buyer-side evidence: reviews where you were the buyer, plus eBay history imported as a buyer account.
Verified trades
Total countable activity: RepDex reviews received plus imported eBay feedback.
Which platforms count
eBay
Verified eBay accounts can pull public feedback score and positive feedback percentage into the trust score and seller score. Best contribution to the headline score.
Verified Reddit accounts confirm identity and contribute a capped standing signal built from public karma and account age — worth at most a third of a maxed eBay account.
Discord
Discord has no public profile lookup. Accounts are verified manually and appear as a platform badge. Reviews tagged Discord are tracked but marked unverified.
Why is verification required?
A platform link only contributes to your score once it is verified. Verification proves that the RepDex profile actually owns the external account, preventing someone from claiming another trader's reputation. Manual verification is used for platforms without public APIs or profiles.
Recency weighting & red flags
Reputation ages, so recency is built into the score itself: every review's weight halves each 12 months. A clean run from three years ago can't hide how someone trades today. On top of that, red flags call out patterns the number alone would smooth over.
- No activity in 12 months — no reviewed trade in the last year, so the score is stale.
- 3+ negatives in 30 days — three or more reviews of 2 stars or lower landed this month.
- Trending down — the last 90 days average a full star below older history.
Flags are signals, not penalties — they never subtract from the raw score, they just tell you how to read it.
