How the TradeProof trust score works
A transparent 0–100 score built from public Steam data and community evidence. The same input always produces the same score, and every point is explained on the profile.
The seven signals (100 points)
| Signal | Max | How it is scored |
|---|---|---|
| Ban record | 25 | No bans: 25. One VAC ban older than ~5.5 years: 15. One recent VAC ban: 5. Two or more VAC bans: 0. Each game ban: −5. Trade-banned: 0. |
| Account age | 20 | Under 6 months: 0–4. 6–12 months: 5–8. 1–2 years: 9–12. 2–5 years: 13–17. 5+ years: 18–20. |
| Steam level | 15 | Level 0: 0. 1–5: 3. 6–10: 6. 11–20: 9. 21–50: 12. Above 50: 15. |
| Community standing | 15 | Starts at 15. Each confirmed report: −10. Each pending report: −3. Never below 0. |
| Game library | 10 | 0 games: 0. 1–5: 2. 6–20: 5. 21–50: 7. More than 50: 10. |
| Profile quality | 10 | Public profile: 5. Custom avatar: 2. Persona name set: 1. Public with a level: 2. |
| Verified trader | 5 | Reserved for traders in the verified-trader programme (not yet open), so nobody has it today. |
Hard caps
Some facts override the points total, because no amount of good history should outweigh them.
| Condition | Effect |
|---|---|
| Listed as SCAMMER in the archived SteamRep database | Score capped at 10, verdict “scammer” |
| Listed as CAUTION in the archived SteamRep database | Score capped at 55 (never “safe”) |
| 3 or more confirmed community reports | Score capped at 5, verdict “scammer” |
| Steam trade ban | Score capped at 15 |
| 3 or more VAC bans | Score capped at 10 |
Verdicts
70–100 safe, 40–69 caution, below 40 danger. “Scammer” is shown when an account is listed as SCAMMER in the archive or has three or more confirmed reports.
Where the data comes from
- Steam’s public Web API: profile, level, game count, VAC, game and trade bans. Refreshed at most every 6 hours.
- The BANNED and CAUTION archive that SteamRep released to communities when it closed (2024 export).
- Reports submitted by signed-in users and reviewed before they count as confirmed.
Limits you should know about
- Private profiles hide several signals, which lowers the score. A low score means “less evidence”, not “guilty”.
- The archive is a historical snapshot, not live. Accounts can change hands.
- A new scammer with no history and no reports can score like any new account. A score is evidence, not a guarantee.
- We do not read inventories, trade history or messages.
