Ask HN: Data Sharing on Fraudsters
Is there intel data on fraudsters on the internet? Would that be legal/GDPR-compliant? Talking about emails, phone numbers, faces, etc.
There are public suspicious IP address lists/lookups but nowadays fraudsters with any level of sophistication tend to get a fresh IP each time.
It's a hard problem. You have to decide who you can trust to submit "fraudsters" data and to what extent you trust what they provide. If you start looking at PII (emails, phone numbers, faces, etc. as you say) then even good actors may inadvertently add data of innocent people that fraudsters are fronting as.
On the other hand, yeah, I've seen services that share this kind of data like Sift and seon.
I'd never thought about this "tainting" aspect though. Good point.
