Use this when you want to block purchases from customers with a specific tag, such as customers who have engaged in disruptive behavior or customers whose purchases you want to restrict.

Result

Customer status	Result	Reason
No `blacklist` tag	Allowed	Customer does not have the blacklist tag
Has `blacklist` tag	Not allowed	Customer has the blacklist tag

Configuration example

③ Eligible items	Set the products or collections you want to restrict
④ Product message	Enter any message
⑤ Alert message > Display timing	Cart updated and checkout
