One of the reddit comments says: > Zelle isn't problematic if you use it for its intended purpose and don't send money to complete strangers Why does it matter whether you're acquainted with the recipient?
The only time you’re using these apps for payments to unknown 3rd parties is buying on the used market. For local buying, you meet in person, in which case Zelle is fine since you can see the goods. For remote buying (like r/hardwareswap), you’re supposed to use something with protections like PayPal Goods and Services, or /also rely on the platform.
There are phishing scams associated with PayPal too, for example.
