Seems to be working great. It would be nice if I could define custom attribute & value for blocklist or at least we had a phone number block list alongside email blocklist. I would like to block customer by email as well as phone number.

Remove a note from a customer's order for no reason. Idk if it was a glitch but because the app auto removed the customer's note even though they were not flagged and we ended up missing the note asking us to hold their order and ended up getting a chargeback from the customer cause we sell perishable products and the customer was not able to be there to receive their order and blamed us for not seeing their note which was removed by Bad Customer so we are now having to deal with a chargeback and probably are going to lose money on that order.... Been using it for months and haven't seen any value in it as the app also auto tags all the trigger tags even if only 1 trigger is activated which is not helpful... Its yet to identify a bad customer and prevent a person who is clearly a serial chargeback fraudster...

I used this app to help stop repeat offenders from being able to make purchases, loaded all the information required (address and zip) for every previous chargeback customer and in the 12 days it has been installed we have had 3 orders come in from previous chargeback customers go through without being tagged. Further more we have had new chargeback customers in that week and when you use this app to scan for bad customers it says this customer has no chargebacks or refunds. I can assure you this customer has $xxxx amount of money in chargebacks and 7 orders but the app reports 0. I reached out to their support 3 times and have not heard from them a single time in the 12 days.

Would be a good app if it actually blocked bad customers. All it does is email an alert which is easy to miss prior to processing the order.

I like that this app monitors for problem customers from multiple databases at the time the order is placed. By adding to my own blocked list, this app helps me keep track of customers I don't want to sell to (Multiple returns, too much drama, one-star review because of the post office, etc). The blocked list just reminds you. You can still process the order if you choose to. Excellent app with excellent support. Highly recommended.

Definitely a clever approach to fraud detection. Great app! Our Shopify store syncs with our warehouse automatically, so even if we did notice something that seemed suspicious, the warehouse had usually already packed and shipped it. We were able to configure our 3PL to ignore orders with the bc_warning tag so they didn't automatically ship and can just remove the tag if we want to take the risk and ship it anyway.
