We've had a few fraudulent credit card transactions (stolen cards used for purchases, followed by chargeback later), so I'm looking at ways of reducing the risks.
Looking at the PayPal Website Payments Pro settings, I noticed the Fraud Mgmt Filters is set to off. Do most people have this off or on? Is there any benefit in having it on?

I'm not convinced the module does all the checks it should be doing, so looking for ways of beefing this up.

Thanks!
