Hello
iam searching for a theme or plugin where user can create social profiles and rate/review products (like ejuice/eliquid). When the product is not in the database user can submit the product where a moderator or admin can approve it.
User can follow each other or can follow the brand or product.
I hope u understand what a mean 
my english is not the best
How about this theme? It’s the closest I could find to what you’re looking for. 
The only thing it doesn’t have is moderation so you would either need to get that customized (check out Envato Studio for customization) or do it manually.
Yes, this is the case, but in your example the admin or moderator must have already written a review. I need something like just product maintenance. I just put the product with the description in… User rate it. That’s it! And if a product is missing, users can enter it.
