In easyPoints, you can exclude specific customers from earning points through orders by tagging them.
How to set up
Open the customers tab in your Shopify admin, an click on the customer you want to exclude.
Add the tag no-easy-points from the bottom right tag section, and save.
Once saved, the customer will not earn points through orders.
It can be reseted by deleting the tag, but the points that were ignored while tagged will not get recovered.
