Tea, an app that allows women to post anonymous comments about men they’ve supposedly dated, announced Friday that it has suffered a data breach, with hackers gaining access to 72,000 images.

The application found itself atop Apple’s App Store earlier this week after hordes of new users signed up to the app.

Tea has gained increasing popularity, saying on Instagram that more than two million users in the past few days had asked to join the app. Signing up for Tea requires users to take selfies, which the app says are deleted after review.
