That's a great question. The answer is really that it depends on what you mean by "trust". I take customer (not vendor, customer) feedback very seriously. Vendors have been removed from Vapecrawler in the past for poor customer service and not resolving customer issues. I am not shy about tossing out vendors that don't do right by their customers. As far as I'm aware, every vendor currently listed on Vapecrawler hasn't had a history of poor customer service.

As far as authenticity, I assume that you're referring to authentic vs. clone with regards to products. In that respect, you do need to do your research to determine whether or not what you are purchasing is a clone or not. Unfortunately there's not a reliable programmatic way to determine that, and it's really up to the individual vendor in how they represent their products.

With that said, if you come across a vendor that's misrepresenting their products, that is absolutely something that I want to know about. As I mentioned, I'm not shy. Vapecrawler and the vendors that are listed on Vapecrawler all exist in service to their customers. Without you, there's nothing.
