Brushing is a deceitful technique sometimes used in e-commerce to boost a seller’s ratings by creating fake orders.
Most e-commerce sites rate sellers by multiple criteria and display these seller ratings to customers. Since a good rating can boost sales, these ratings are very important to sellers. The number of items sold is usually an important factor in that rating. Brushing consists of generating fake orders to boost the rating.
A seller can do this by paying someone a small amount to place a fake order, or just using another person’s information to place an order themselves. Because a shipment usually has to take place for an order to be considered valid by the e-commerce site, the seller will frequently ship an empty box or some cheap item. These fake orders, if unnoticed, can boost the seller’s rating, which can make it more likely that their items will appear at the top of search results on e-commerce sites.
Many e-commerce sites have recognized the problem and claim to actively combat brushing. One company that has received a lot of attention is Alibaba, and in the prospectus they published before their initial public offering they even mentioned the problem. Brushing also inflates the numbers reported on a company’s financial statements, and therefore it also attracts the scrutiny of investors and market regulators. For instance, the US Securities and Exchange Commission opened a probe to investigate the validity of their data when Alibaba reported revenue of more than $14 billion on Singles Day.
In July 2019, consumers were warned to be wary of unsolicited Amazon packages following reports of individuals receiving packages they never ordered as part of such brushing schemes. In Amazon’s system, those making the original purchase are allowed to leave a verified review for the product, thus boosting the rating by posting a fake five-star review. The customer’s address may have been previously obtained by a third-party seller, or even through a simple Internet search. While receiving such packages may not necessarily indicate any greater problem, they could in some cases be indicative of a data breach. Customers who believed they may have been the victim of brushing scams were advised to immediately notify the retailer in question, as well as change their password and possibly utilize credit-monitoring services.
In July 2020, thousands of packages of seeds marked with false descriptions such as earrings were received all over the world from China. The mysterious seeds caused biosecurity concerns but were thought to be another brushing scam. Authorities such as DEFRA and USDA investigated and Kentucky agriculture commissioner Ryan Quarles said: “We don’t have enough information to know if this is a hoax, a prank, an internet scam or an act of agricultural bioterrorism”. China Post said that the mailing labels had been forged while Taiwan intended to fine a Chinese logistics company for transshipping contraband.
In September 2020, an article by Motherboard which summarized the result of Freedom of Information Act requests relayed that a Utah lab reported, “Our seed lab has identified the following: rose, amaranth (not Palmer), 2 mints, False Horse Balm, Self Heal, Lespedeza and Sweet Potato.”
In late September 2020 the Utah Department of Agriculture and Food announced that Amazon had agreed to a voluntary US inbound seed quarantine – that is to say, they will delist seeds from outside the US that any seller attempts to sell into the US. The American Seed Trade Association gave a statement saying that this was their understanding also.
On Tuesday, September 29, 2020 the Brazilian Ministry of Agriculture said it had so far received 36 complaints about unsolicited seeds. These reports came in across eight states.
By the beginning of October 2020 the USDA and Louisiana Department of Agriculture and Forestry considered the mystery largely solved, blaming both real seed orders that were merely mailed from locations the buyers did not expect, and truly unsolicited mailings.
Alibaba and eBay’s plant security practices were investigated by James Comer, Ranking Member of the House Oversight and Reform Committee, at the start of October 2020.
Seed mailings have occurred again – after a hiatus – in October 2020 in Marion County, Alabama.
In November 2020 Arizona’s Department of Agriculture said that seed mailings had slowed but not stopped. Most reports were from the Phoenix and Tucson areas although the entire state had reports. The seeds were ornamentals, fruits, vegetables, herbs, and wheat. These seeds have the potential to spread viruses and other diseases.
In November 2020 the Australian Department of Agriculture said that they had received 228 reports and decided to start using a new X-ray system. Unlike the existing x-ray scanners used at borders, these will use automated processing of the x-ray images themselves, which the DoA expects will yield more thorough results. For those seeds that still slip through the Department has also asked Australians to report using a website (see #External links).
