Great experience for us so far. Filled a gap we had in our current tooling, definitely a huge recommended essential item for back office, fraud prevention for anyone. Part of my personal day 1 installs here now.

Great idea for sharing blacklist across all stores using them. Hope more people use them ASAP. However need these improvements: 1. to allow adding of customers to the blocklist via tags. (Update: they implemented this, working) 2. Prevent blocked customers from checking out in the first place, not cancel after they paid. (In progress)

Unfortunately, we're still getting chargebacks due to orders being flagged high risk but were not put on hold by Blox. Thanks.

The helpful insights are super easy to use for our customer support agents, and this gave us a great grip on fraudulent orders. We were able to literally get rid of all our return and replacement abusers.

blox is our new favorite employee. it caught a blocked person (return fraud) who kept making new emails and still caught every one of them. Absolutely legendary and so satisfying to watch

Looooove blox. We have a huge issue dealing with a ton of return fraud/abuse as well as weird customer behavior. Been using Blox to find unprofitable or problematic customers and cut them out of our customer file to save us the operational and financial headache
