Choose the countries, IP addresses and ranges (IPv4 and IPv6) you don't want, or allow only the countries you sell to. Blocked visitors see your block page. This runs in the browser, so it keeps casual visitors out but can be bypassed; the checkout rule is the enforced part: every checkout, express included, stops for blocked shipping or billing countries, emails, domains and customer tags. New orders from blocked IPs or emails are tagged for review. Search engines are let through.
