What about the legalities behind using it? I am curious if anyone has actually spoke with a legal team as to the implications of using such a service in either the USA or EU?
The sharing of client information is typically a very big "no no".
We use FraudRecord in addition to Maxmind as well as our internal Verifications team. With the 3, we have had only 1 spam account get past which is pretty dang good in my mind.
Fraud record is a great service and definitely worth supporting. We are currently a sponsor for them aswell.
The Fraud Record system uses hashes for the data stored on their servers, so no undecoded data is actually stored there.
I use Fraud Record all the time, I just wish that the fraud system in whmcs would allow you to use multiple fraud checking systems instead of just one.
