How to hide a product in colleciton page by the customer tag

[John-CC]

we have a business rule that to avoid customer (with certain customer tag) to view specified prodcut in our store.

but when we try to hide with below liquid in our collection page : 

{% for product in collection.products %}  {% unless product.tags contains 'your-tag' %}
    <!-- Product HTML here -->
  {% endunless %}
{% endfor %}

There will be problems with paginated display 

May i know is there any good practice to implement?

but as you known , we seems cannot have a dynamic collection by the customer tag .
