Update: the App Review Board has confirmed that my Apple Developer account will not be terminated. Sparrow on macOS is safe.
Thank you to everyone who shared and reached out in the past 24 hours - I'm grateful. Credit to Apple for reviewing the appeal and reaching the right outcome - it could have gone another way.
The deeper problem hasn't gone away: apps impersonating Sparrow Wallet are still reaching users and putting their funds at risk. I'll keep working on this, hopefully with Apple's support.
The situation needs to be brought to the attention of Apple’s App Review board. Unfortunately X is probably the best way to achieve this, otherwise my appeal may never be reviewed by a human.
I created a placeholder iOS app for the App Store to warn users about scam “Sparrow” apps, of which there have been over a dozen.
The app was never published, but Apple flagged it (a year later) for “dishonest activity” and will terminate my Apple Developer account on June 30 unless the decision is reversed.
Unless Apple’s decision to terminate my Apple Developer account is reversed by June 30, all new installs of Sparrow will fail, and development on macOS will end.
