MaxMind is good, but 2.33 is to strict. We have it at 4 and its doing good.
Anyways, it doesn't stop the real scammers. And, there are points where it goes to errror.
Like with WHMCS, and MaxMind, when client signs up, enters phone number, if its entered wrong, of course it won't work.
Ex.
1.8881110001 (wrong way because of decimal)
The bad part is, it cancels the order completely, which is a problem with us right now.
