Products listing issue needs solution

-- HikaShop version -- : 4.4.2
-- Joomla version -- : 3.9.25
-- PHP version -- : 7.4.14

Hello

We have an issue with our multivendor e-shop.

We have created the categories where the vendors can list their products. (They can list their products only at the end level categories like this...

Products category
» Category 1
» » Category 1a
» » » Category 1b
» » » » Category 1c (This is the category that has the products. All the above categories have no products)
» Category 2
» » Category 2a
» » » Category 2b (This is the category that has the products. All the above categories have no products)
» Category 3
...etc

We use the HikaShop » Products listing menu to list the products of all vendors and the filters, so that visitors can select what they search for.

The problem that we have is that some vendors sell adult or smoking products that have to be shown only to adults. So the result is that if a vendor sells mobile phones (for example) they appear side by side with the sex shop (for example) products. So we get complains from some of our vendors that we do not respect their reputation (from one point of view, they are right). Also it is not nice to show mobiles and sex shop products side by side.

So... we have to find a solution to exclude products that belong to certain categories from showing on Products listing page.

Please give us a solution...

Thank you.
