Scamalytics alternative — don't trust one fraud score, see 8 sources

Scamalytics gives you one number: a 0-100 fraud score. It looks clean, but it compresses signals of different natures — is this a datacenter IP, any recent abuse reports, is it a proxy exit — into a single value, and you can't see which one pushed it up. For programmatic blocking that's fine; you set a threshold and move on. But when you're doing manual due diligence and need to judge whether the verdict applies to your case, no reason means no judgment.

The more practical issue is single-source blind spots. Any risk-data vendor has its own collection scope and update cadence for proxy databases, abuse reports, and blocklists. An IP that looks clean to Scamalytics might still be flagged elsewhere as a Tor exit or listed on Spamhaus. Trusting one source is betting that this one source happens to cover the risk you care about.

IPOK doesn't "replace" Scamalytics — it puts it back into a multi-source view, since Scamalytics is one of IPOK's 8 aggregated sources. On IPOK you get Scamalytics' verdict together with ip-api, ipapi.is, proxycheck, AbuseIPDB, StopForumSpam, IPQS, and the in-house IPOK-DB, side by side. Which source calls it a proxy, which has abuse records, which considers it clean — all visible at a glance.

The key layer is the hard-signal floor: decisive signals like an authoritative blocklist hit or a confirmed datacenter IP force the score into the high-risk band and won't be averaged away by optimistic scores — a tool that only does weighted averaging is exactly where genuinely dangerous IPs slip through. Add native/datacenter classification and a /24 neighbor profile, and you get not an isolated score but an evidence table you can review yourself. All free, no signup.
