Businesses often underestimate the consequences of multi-accounting. Let’s find out when it can become an expensive issue and how to prevent it.
Mark saw that his favorite carsharing service is offering lucrative discounts for new customers. He decided to take advantage of this promo by creating another account. Is this a crime?
What Mark did isn’t exactly fraud, but if the service prohibits multi-accounting, he certainly violated the terms and conditions. Similar instances of account misuse can be seen across multiple online industries, such as e-commerce, gambling, betting, gaming, dating, travel, and food delivery.
Multiple account misuse has surged along with other forms of online fraud during the pandemic—when consumers rapidly transitioned online and businesses offered perks to attract them.
Multi-accounting is when a single user registers multiple accounts to take advantage of an online service. This can be done to repeatedly benefit from free trials, discount codes, and other bonuses—or to continue using the service after getting banned.
Multiple accounts may seem benign; for instance, people can often have both public and private social media accounts. But when it comes to online services, multi-accounting can be used for a range of fraud activities (which we’ll cover in more detail below). For this reason, companies that detect multiple accounts being created or accessed from a single device should consider this a red flag.
Many companies explicitly prohibit having more than one account, but some users find ways to get around these restrictions. In fact, you can find tips on this practice on forums and Youtube videos, which offer detailed explanations on how to multi-account without getting caught.
Multi-accounting methods can range from basic to complex:
There are various reasons why people conduct multi-accounting:
All in all, multi-accounting creates different problems depending on the site platform or service targeted.
Any business can become a multi-accounting target, but the following businesses are most likely to suffer:
These are decentralized platforms where the buyer and the seller transact directly with each other. People use such platforms to sell things, offer services, and post tasks for qualified professionals. Fraudsters can create multiple accounts to swindle others—for instance, by selling fakes or asking for prepayment and disappearing with the money. If unchecked, these practices can cause the marketplace or service to lose a significant number of honest customers.
In recent years, online marketplaces have become ripe targets for promotion abuse and affiliate fraud. This refers to the repeated use of sign-up bonuses, referral bonuses, and vouchers from multiple accounts.
Multi-accounting has been a huge problem for gaming and gambling platforms since unscrupulous players can enrich themselves by selling accounts and certain resources. For instance, players can sign up on multiple accounts to amass free gifts intended for newcomers and resell them.
Bettors can use multiple accounts in order to conduct arbitrage betting, a practice otherwise known as “arbing.” This refers to a strategy in which bets are placed on multiple outcomes to guarantee a profit. Arbing is legal but bookmakers don’t welcome this practice because it costs them money. However, it’s typically difficult for bookmakers to identify and track arbers.
In the travel industry, fraudsters use multiple accounts to write fake reviews, which travellers heavily depend on when booking their vacation. Accordingly, a single negative review can be costly for any travel company. Multi-accounting is also used for fake bookings to get onboarding perks. What’s more, there are fake accounts resembling real travel agents.
The online dating industry is full of romance scammers and fraudsters that use multiple accounts to reach more people. Statistics show that 30% of U.S. adults use dating apps or websites, while romance scams caused $304 million in losses in 2020, underscoring the vulnerability of the industry.
For instance, Simon Leviev, the famous tinder swindler, created several fake identities to date with dozens of women around the world. Then he managed to establish lines of credit and loans in their names, ultimately leaving them holding the bills.
In the aftermath, scammers created plenty of fake ‘Simon Leviev’ accounts as The Tinder Swindler went viral. They make money from fake fundraising campaigns created to allegedly support Leviev’s victims. In other cases, Leviev’s identity has been used to promote legit businesses such as NFTs.
