What do you mean by drop-shippers and what do they do that's risky/bad?
Looking for drop shipping on Google leads me to pages e.g. by Shopify or Square explaining it's a model to run retail where the store doesn't hold stock or fulfill but instead has a distributor / manufacturer fullfil the transaction, shipping directly from them to the customer.
Some companies don't want to do business with drop shippers, maybe because they will often be unable to fulfill orders or because customers will often be upset that their order took a few weeks to arrive. As a manufacturer, we anticipated that some people would resell our products on their own storefronts.
