Blockly Fraud Filter, Blocker

I was having fraud orders on my $2 digital items multiple times a day. The whole point of a digital item is the instant delivery, so I didn't want to have to change the way the item fulfills to prevent chargebacks. I tried this and I am only on day 4 but have not had a single $2 fraud order since! I appreciate the ability to also block user names & addresses since one fraudster was using the same fake name & fake address over and over. So far, so good!
