Twitter launched its “tip jar” feature on May 8, which enables users to send money to others via third-party applications. It is an “easy way to support the incredible voices that make up the conversation,” said Twitter. This feature, however, is currently only available to a small group of individuals such as content creators, journalists, experts, and non-profits. A small icon that has a drop-down list of different payment providers popular in the U.S., such as PayPal, Cash App, and Venmo, can be seen on the user’s Twitter profile. This feature is only accessible on mobile devices for the time being. However, recipients reported seeing the sender’s postal address when tipping through PayPal.

Security expert Rachel Tobac publicly pointed out the privacy issue, and Twitter product lead Kayvon Beykpour explained that the company cannot control how PayPal manages personal data. PayPal, on the other hand, explained that Twitter’s tip jar feature uses its “goods and services” option, which shares the sender’s and the receiver’s shipping information. PayPal recommends switching to the “friends and family” option to hide personal details. This function will soon be available to more Twitter users, but they are worried about its privacy concerns. Journalists, on the other hand, are prohibited from taking tips, so it is unclear how news organizations will handle this feature.
