As from the top of the suppliers section
"These forums are run by Suppliers whose customer service standards we monitor carefully."
That said, you can make ejuice in your bathtub and still be 'endorsed' here as long as your customer service is good.
Did you read the line you bolded? "Customer Service Standards". It has nothing to do with facility cleanliness, or facilities at all.
It's a line we put in so that if a vendor repeatedly screws our members over, we have cause to remove them from the ECF.
Our answer was given above. This is not something that a few forum volunteers can do. I suggest that if you have questions about a vendor's facilities, you should ask them directly. If the answer they give is not satisfactory to you, then you have every right to not purchase their products.
