Can you block a specific user from seeing product pages?

There is a problem user who keeps buying products then stealing the copy (it's rather unique copy) to resell the products elsewhere. What I would like to do is block them from even seeing the product pages so they can't see the copy or even buy the products. Is this possible and if so, how? I have the user's email address and IP address already.

Quick thought. You could use Liquid with {{globals.user}} or {{globals.visitor}} to check for those values since you said you have both. Basically if {{globals.visitor.ip}} == Problem User's IP value then show a different page or content with a page.

Thank you very much for responding so promptly and for the great advice. I'm not proficient in coding to begin with and it's been a while since I've done it but this is what I ended up with and it seems to work even though it's not pretty:

        {% if globals.visitor.ip == "123.456.789.100" -%}

        <script type="text/javascript">window.location.assign("/404");</script>

        {% endif -%}

        {% if globals.user.email == "NotReal@fictional.com" -%}

        <script type="text/javascript">window.location.assign("/404");</script>

        {% endif -%}

Thanks again!

Many people have a dynamic IP range so that can change making that a bit useless.

Logged in users you can just have conditions based on them. You could have a custom CRM field for customers, assign a status for certain users and if that user has that then you can block access.

In terms of logged in users you can drop a cookie for a certain use cases and if it sticks (not blocked) then you can read for that cookie with liquid.

Hi Liam, Thanks for the info!

If you know of a way to keep her from going through the guest checkout which doesn't require a sign in then I'd love to know it. That's where we are currently stuck at. Even if we block her IP and her email which she has used to create multiple accounts, we still can't stop her from going through the guest checkout. Any ideas? Thank you!
